Today's Urlesque Show features a classic prank, a zoo friendship, and an impromptu family room game.
First up is a woman who has no idea her friends have rigged her plastic chair to collapse when she sits in it.
Next is a chimp who's either really mad at this baby, or really wants to give him a high five. We can't quite tell.
Finally we have a dad and baby who have discovered a fun new way to play peek-a-boo with the dog.
Check them all out, and be sure to let us know which is your favorite viral video of the day in the comments.
