Tear Jerker: Phelous
The entirety of his Sonic Christmas Blast review, he basically breaks down in the middle of the review several times to cry. The reason for this? He (ghost)busted Santa Claus in his last review. To add to injury, after Sonic is declared the new Santa, he celebrates the fact he's off the hook, and he accidentally steps on the trap, and busts Sonic Claus. At the very end, he declares that Christmas is over, and there is nothing he can do about it.
The ending of his and Lupa's review of Julie and Jack is surprisingly effective, even though it was just a silly take that to that films pointlessly sad ending. The fact that it just leaves off on Phelous crying on the floor when you'r expecting Lupa to jump out and say "Got ya!" is strangely depressing.
The ending of the Octopus 2 review. Phelous crying on his tricycle. Sniff...
