Ep 6. I Only Have Surprise for You

Much to the objection of Mac, Bloo throws him a surprise party every year and Mac has reason to believe that today is that day. However, the parties include little celebration and more humiliation. But this year, Mac is determined to thwart the party before Bloo has a chance to embarrass him. He suspects that all the imaginary friends are in on it and becomes very paranoid about every small occurrence, confident that each minuscule event is part of Bloo's big scheme.
