Serious Sam 2, which I will argue is still the best game in that franchise. It's nothing like other FPSs; it's cartoonish & silly & bright & colorful.
I have a weird thing where I actually find something that is over-the-top offensive strangely alluring (I blame Japan), so despite the fact that I should be highly offended by it seeing as I'm a chick & all, I got a good laugh out of Duke Nukem Forever.
I also have an even stranger fondness for abysmal wrecks, be it no-budget indie horror films with shit actors & a terrible script, or laughing for half an hour at the biggest failures in video game history. Well, I actually get a much bigger sadistic kick out of watching miserable or angry people play them, like I was Satan sucking up the essence of misery as if it was chocolate. I also looooove sarcastic reviews where the actor pretends like the game is awesome.
Angry Joe reviews Thor: The Movie: The Game.
NoNameGuy reviews Big Rigs: Over the Road Racing.
Kikoskia reviews Crazy Bus.
Peanutbuttergamer reviews Hey You, Pikachu.
JonTron reviews Aquaman: Battle for Atlantis.
Lastly, the other kind of wrecks; the ones with hilarious non-game-crashing glitches & impossible physics. I can tell you right now that I suspect that people who share my love of this are the ones demanding new FIFA, wrestling, Skate, & probably Madden every year; the most hilarious things happen.
