What a waste of the Internet.

And television

Is it me or is this not funny at all?
It's actually terrible.

"haha" :/

I wanna know the name of the guy who invented automated laughter

Rubbish, drival, gutter TV quit and do something usefull. Oh and if you watch his show you should also conisder suicide.

I feel like punching his face repeatedly

who give´s a fuck? this is pure crap

Geez, violence, suicide?! Don't get excited. Letterman actually has a decent late night show, the top ten is kind of standard. That was a Transformer movie plug done buy his writers (bosses), you could tell if you have watched the show he wasn't very impressed with it either. Before anyone goes off I suggest watching some Mr. Rogers re-runs.

nr. 10: you'll rust don't do it, it has ironeating microbes, true thing
nr. 9: it will only tear up when you transform, you silly juice, hahaha optimus, you're sooo funny
nr. 8: robot is not a feminine word in ANY language, ice cream is ok, but... you're damn robot, without a mouth..
nr. 7: I'm not even going to critisize that one, it almost made me cry...
nr. 6:you suck at humor, stop it, seriously, blast the squirrel, trample it, you're a giant robot for christ's sake
nr. 5: (i can't believe i'm actually commenting em all) pitchy?? DAWG?? see nr.6 for advised course of action
nr. 4: it's FB, no one cares, everyone knows already, cause it's FACEBOOK... people know who added you before you do
nr. 3: it's a thursay actually thank you, you should go to the garage for a check up
nr. 2: robots are logic beings, you don't believe in God, because you can't even understand the concept (of believe and such)...
nr. 1: *puts shotgun in mouth*

i actually watched the whole movie, AND commented it ALL, i just realised, when you can't sleep, you are really REALLY bored... (and I seem to have no life)

Letterman doesn't even find it funny... it looks like he was forced to do it!

This is as funny as cancer.

Good night kainim, when you wake up it'll be "A beautiful day in the neighborhood".

just like to put it out there, if i had a chance i would have definitely rejected this crap

I have never been able to understand American humour

#15, i had a jolly good night, except from 1 horrible dream, where they invited megatron to letterman

Wow first time people getting thumbs up for saying the vid sucks.

supposed to be sold by the fact that letterman had bay animate optimus prime and voice him. Terrible waste of time

I wasted 3 min on this rubbish?! Should have read the comments first....

what "sucks" is actually the transformer movies. poor letterman, having to cope with the crap the world comes up with
