But, lame as the accent is, Braslavsky is not. Decked out in a Hawaiian floral print and pencil mustache, Braslavsky is performing a performer, making a stereotype of a stereotype, and taking a certain amount of glee in his racially charged Droste effect. His comedic rhythm, always a patient beast of long silences and telegraphed setups, slows to an epileptic crawl and the character, “Hector Arroyo,” tells long story-jokes, each punctuated by a DJ blasting jumpy, Tito Puente-style mambos. As bits go, it skews somewhere between cute, offensive, and brilliant. But he knows this crowd. He trusts them. And, as expected, they eat it up.
