The best moment for me would have to be when I first began New Vegas. I was outside of the saloon, learning to shoot and she told me to shoot at the sarsaparilla bottles but I didn't know where they were so I shot a bighorner. Well. All hell broke loose. The bighorner turned hostile, cheynne charged it and began attacking it and then easy Pete showed up and started chucking dynamite at the two. Once the dust settled, sunny, cheynne, several settlers and a bighorner lay dead. Needless to say I deleted that file and tried again.

When I got close to Deathclaw Promontory and my game froze. I was like: What the-bighorner offspring?

on my second playthrough i was level 2 or 3 and went to the 'ol bone orchard to get a broc flower and do a little grave robbing. after looting the first grave i turned around and there it was, a full-grown deathclaw. 0.0

i never did rob those other graves....

also after getting the game at midnight release, me & a friend of mine decided to just both go to my house, i knew if i started playing i would never be able to stop & go to bed, so he played it first. first gecko he killed for that tutorial and guess what...

froze. -_-

A legion dude just fell out of the sky in front of Vault 22 and killed the mantis for me. Was like kaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay

I ounce shot the Legate in the head and I never saw him again. Only found his eyeball and this chunck of human meat after. It was pretty funny, funnier because it was like 4 in the morning( everythings funnier when you're tired )

Sick, I got a star

I thought the PS3 patch was available in Europe, but it wasn't. So I waited 24 hours, and it still wasn't. So then I waited another 24 hours, and it still wasn't, so I was like WTF?

I saw a bighorner humping a fence and I was like: What the-cat in the poptart?

The first time I met the BoS.

That also reminds me of the BoB. It was full of WTFness.

I was killing fiends when I found a crafting part for over 3000 caps and weighed 5 pounds. I nabbed it, took it to gun runners, and it would not show up on the barter screen. I backed out, looked at my inventory, and it showed it. I can't sell it then i used the vendor caps glitch and nabbed two high powered weapons

I went to some house that's surrounded by 10-15 cazadors, and I killed half of them with the paladin toaster. When I first saw a cazador, I didn't see anything else but my last save. Now I killed 7-10 cazadors in one go!

Mr. House denying me. That was a huge WTF moment.

Other than that, there was this one time coming out of Brewer's Beer Bootlegging and getting assaulted by half a dozen Cazadores that were NOT there when I went in. That was a sore throat from screaming curses at my television and almost a smashed controller.
