Not a fan, but stumbled upon this at

the Portman rap though I don't watch "SNL" anymore. Funny clip.
I first heard about "The Lonely Island" & Adam Sandburg on an MTV site, which I actually thought they uploaded actual clips from vintage "MTV Spring Break", but got punk'd instead

I thought "On A Boat" was dumb and noticed since the song sounded modern that I knew something was different... despite my lack of knowledge of the comedians. (Yeah, I'm sometimes too gullible

)
Though ironically, I find many songs from the past decade unintentionally hilarious like "Rehab" from Amy Winehouse, "Beautiful Girls" from Sean Kingston, and some rappers & emo acts...
