Ke$ha-Tik Tok I thought it was sorta funny, the parody seemed some what better then the actual song. Not to give Kesha too much credit but yeah...
White and Nerdy, it's Weird Al
the farmville spoof of one time by justin bieber
Any Weird Al song. My favorites are angry white boy polka and amish paradise
Not Afraid by Key of Awesome =]]
TIK TOK THE MIDNIGHT BEAST
Probably Tik Tok parody by thecomputernerd01
