"So Fresh, So Clean" (OutKast)

There are so many songs in OutKast's catalog, including quirky/obscure album tracks, that I love.  But I can't help but choose the single "So Fresh, So Clean" from Stankonia (2000) as one of my favorite tracks.
Basically, it's just André 3000 and Big Boi spitting freaky deaky come-ons over a tasty, tricked-out Organized Noize beat for 4 minutes.  But the scenarios they sling are just so wrong that they're right: they call up everything from Noah's Ark to Anne Frank in their quests to get some luvin'.
My favorite pick-up line of all comes from Big Boi: Teddy Pendergrass / Cooler than Freddie Jackson sippin' a milkshake in a snowstorm.
Game doesn't get colder than that.
