We're not sure what about the pairing of a tall, skinny man and a short, stocky one equals pure comedy gold, we just know that Yamil Piedra and his diminutive friend Johnny Trabanco use it to great effect. The unfortunately monikered A Pair of Nuts was awarded Best South Florida Performance at the 2007 Miami Improv Festival (which is no small feat in Miami's burgeoning improv scene) and was featured on BET's We Got to Do Better. Tonight's Miami-flavored, multimedia, sketch-comedy gig at the Improv will evoke everything from SNL to Sábado Gigante.
