In retrospect, it's hard to believe the gang hasn't formed a band before now. When you're talking style over substance, you're talking rock and roll. And isn't that the whole Sunny premise? Every episode could be called "The Gang Adopts The Shallow Veneer Of A Lifestyle."
Here it's Dee's rapper boyfriend Kevin — possibly retarded — who gives Mac the idea to start a band. "If he can do it, why can't we?" he reasons. "I can't argue that logic!" Charlie enthuses in response. Surprisingly enough, three out of the four potential rockers seem to have some musical ability: Dennis has the DeYoung vibrato, Charlie "gets" keyboards and fancies himself a Dylanesque poet, and Mac at least knows how to form a power chord. Only Frank on drums is hopeless, but that's true of 70% of drummers who actually have gigs, so you can't really fault him.
If it's not too much to claim — and heck, I claimed it about How I Met Your Mother this week, so I'm on a roll — I'll be so bold as to say there is a Theme hovering near "Sweet Dee's Dating A Retarded Person." That theme, my friends, is this: What Is Rock And Roll? Is it looking good with a guitar? Is it breaking shit? Is it breaking shit in a hotel room that — and this is the crucial point — somebody else is paying for? Is it space-fantasy concept album song cycles about night men who hold you down and come inside you, or day men who conquer the night men with their mastery of karate and friendship? Is it better encapsulated in the band name Electric Dream Machine or Chemical Toilet? Are those contorted hand gestures genial white hiphoppery or evidence of developmental delays? All these questions are raised by "Retarded Person," but the only one that is definitively answered is that the band name The Pecan Sandies is not rock and roll.
Befitting its near miss with thematic coherence, the episode ends with an Actual Climactic Scene: Kevin the Maybe Retarded Next Eminem gets up on stage and delivers a rap that, as I believe the kids say, "disses" Dee. The put-down resembles in form the kind of normal-person outrage that the gang often elicits, but because it's presented in a rhyming performance by someone with the power of local celebrity, it somehow comes across as utter devastation — less funny than savage. That said, Dennis's Ziggy Stardust-rouged recantation of the aspersions he cast on Kevin's mental ability does pull the ending back into Sunny territory.
