Jake Gyllenhaal, Jimmy Fallon

To celebrate the premiere of TLC Sarah Palin's Alaska, Jimmy Fallon wrote a song about the former Alaskan Governor.

Jake Gyllenhaal joined the Late Night host to perform the ridiculously outrageous musical number, "Gonna Eat That Talkin' Sandwich: The Sarah Palin Song." (Why a talkin' sandwich? Because, for whatever reason, TLC reminds Fallon of a BLT sandwich.)
