Pranks! Wacky, silly, fun pranks! Destructive, horrible, embarrassing pranks. On last night’s Jimmy Kimmel Live!, former Saturday Night Live star Will Forte reminisced about a prank he once played on co-star Kenan Thompson, a generally benign (but charmingly so) prank that saw him and Kristen Schaal playing around in Thompson’s dressing room when he wasn’t present and then sending him pictures of the mayhem. This is a classic prank. What could possibly go wrong?
