Christopher's getting his karaoke on in the living room (killer performance, might we add!) when his wife Delaine sneaks up behind him. When she suddenly startles him, his reaction is pure gold! It's one of the oldest pranks in the book, but also one of the best.
And the hilarious pranks don't stop there! Lance Stewart is pulling a switcheroo with his grandma's identical TV remotes, then tricking her into thinking he made her TV voice-activated. When she says a command, he secretly uses the remote behind her back to control the TV. She falls for it at first but eventually sniffs out the shenanigans. Nothing gets past Grandma!
