Right, now that I've lured you in with this somewhat misleading thread title: The purpose of this thread is to bring up unintentionally hilarious moments in film, games, books, history, hell, anything. Get creative. Apart from THE ENTIRETY OF THE FILM DAYBREAKERS, I'd like to submit the latest trailer for "Skyline". Everything's hunky dory until about a minute and 40 seconds in, where a character lets out the most unintentionally hilarious scream ever caught on film.

Here it isREMEMBER: 1 minute, 40 seconds. Watch for it. PS: I don't know if it's just my headphones, but I'm hearing a crackling sound in this trailer. I checked a few other trailers, and the crackling didn't go away. If it's not just my shitty headphones, then I apologize.)

So, discussion value. What do you think is the most unintentionally hilarious moment in history?(Again, get creative. It doesn't necessarily have to be from something fictional, though it certainly can be)

Devil May Cry 3's giant space whale scene. Single greatest moment in gaming. I'm surprised the space whale isn't an internet meme. In fact, everything from DMC3 was so stupidly over the top it was funny.

Any given cutscene from Tales of Legendia. Sheer fucking accidental gold, I tell you!

Persona 3.
Yukari: "Are you listening, dad? I'm doing okay!"
THE RESOLUTION IN YUKARI'S HEART HAS GIVEN RISE TO A NEW PERSONA!
Me: "... What!"

Janny melting at random in D2. You might be wondering, "What the hell is D2?" The answer is, "Time you can't get back. [http://www.youtube.com/watch?v=kBbvh-mQ4eQ]"
