Play American Buffalo

After two additional showcase productions, it opened on Broadway in 1977.

Act I takes place at about 11 a.m. Don, who owns the junk shop where the entire play takes place, has sold a buffalo nickel to a customer for $90 but now suspects it is worth considerably more. He and his young gofer, Bob (sometimes called Bobby), plan to steal the coin back. Bob has been keeping watch on the customer's house and reports that he has left for the weekend with a suitcase. Teach, a poker buddy of Don's, arrives and learns of the scheme. He persuades Don that Bob is too inexperienced and untrustworthy for the burglary, and proposes himself as Bob's replacement. Teach suggests they steal the whole coin collection and more. Don insists on their poker buddy Fletcher going with Teach. Teach continues to argue that he can do the job without Fletcher.

Act II takes place a little before midnight on the same day. Teach and Don make final preparations for the burglary while waiting for Fletcher, who is late. Teach tells Don that Fletcher is a liar and a cheater at cards, and prepares to go commit the burglary on his own. Don tries to persuade him not to take his gun with him when Bob appears at the store. He attempts to sell Don a buffalo nickel, similar to the one Don had sold the customer. When asked where he got the coin, Bob is evasive. Teach suspects that Bob and Fletcher have organized and completed their own burglary behind Don and Teach's backs. He asks Bob where Fletcher is. Bob tells him that Fletcher was mugged by "some Mexicans" and is in a hospital, but when Don calls the hospital, they have no record of his admission. Bob claims that he must have been mistaken about the name of the hospital, but the suspicious Teach strikes him on the head with a metal object. Another friend calls, corroborating Bob's story and naming the correct hospital. Don calls the hospital and confirms that Fletcher has been admitted with a broken jaw. Bob confesses that he made up the story about the customer leaving with a suitcase, and that he bought the second nickel from a coin dealer in order to make up with Don for his failure to keep tabs on the customer. Don admonishes Teach for wounding Bob and orders him to get his car so they can take him to the hospital.

As is emblematic of Mamet's writing style, the play's dialogue is sometimes terse and often vulgar. Teach says "cunt" numerous times and both Don and Teach say "fuck" even more. Racial slurs are also used. By way of contrast, the younger character Bobby only says "fuck" in situations of extreme duress: immediately after being beaten and his final apology to Donny. Mamet's profanity is not employed for shock value, but is rather an integral component of his characters' "profane poetry", which, according to frequent collaborator Gregory Mosher, "worked the iambic pentameter out of the vernacular of the underclass." The characters' sometimes vulgar lexicon, moreover, may be seen as psychologically necessary armor against their brutal environment.

The parenthetical stage directions are straightforward and do not provide line readings.

Critic Frank Rich, in reviewing the 1983 production for The New York Times, called it "one of the best American plays of the last decade." Rich had previously reviewed the 1981 Off-Broadway production, calling the play "brilliant", and noting: "The play, though, is the thing. Working with the tiniest imaginable vocabulary – words like nothing, great, and no, as well as those of four letters – Mr. Mamet creates a subterranean world with its own nonliterate comic beat, life-and death struggles, pathos and even affection... In American Buffalo, he has created a deceptively small-scale tragedy that is packed with the power to explode the largest of American myths."

The 1975 production won the Obie Award, Best New Play and Performance (Mike Kellin). The production won the 1977 New York Drama Critics' Circle Award, Best American Play.

The 1977 Broadway production was nominated for two Tony Awards: Best Direction of a Play and Best Scenic Design (Santo Loquasto). It received four Drama Desk Award nominations, including Outstanding New Play (American), and won for Outstanding Set Design.
