Even Katy Perry herself showing up wouldn't have been as scary. Ok, yes it would.

What do you get when you combine the most awkward time in a boy's life with the peak of a middle-aged man's hunger for youthful web credibility? Basically, you get Logan Fairbanks singing Katy Perry in the shower until his dad pours cold water on him and scares the crap out of him with a gas mask.

Josh and Logan Fairbanks are father and son, known on YouTube as Dad vs Logan, featuring the "good-natured" pranks Josh pulls on his son (see below). I, for one, look forward to the day that Logan pulls the ultimate prank and grows up into a young copy of his father with all the youth and vitality that raising Logan stole from him.
