"It was like when Darth Vader is arriving and everyone's panicked and nervous. It's like, 'How big are these breasts going to be?' 'Cause they were on this quest to find the biggest breasts that they could. And we thought in Shreveport [LA, where part of the filming took place], that would be a double C or something fun like that."

But they weren't. Echo Valley's breasts are a back-breaking 34 NN, which, Neil notes, look like prosthetics.

"We had to ship her in from Texas, and the crazy thing is she has, apparently the largest breasts in America and has another set in the freezer in case somebody tops her record, she's ready to top them."

"Because they don't make implants that big any more, so she bought them off the market."

"It's an amazing rare chance," say NPH about playing himself in the two movies. "Just as an actor, it was so fun. The first one, I was just worried about, because when I found out it was happening I was already written into the script. I didn't know these guys. I didn't know if that was a good thing or a terrible thing or a career-destroying decision. So I was actually a little bit concerned while we were filming it, just 'cause I didn't want to end up signing on, having it rewritten, as movies tend to be during the process, and then being sort of the butt of the joke instead of part of the joke. I'm so glad I signed on for those three days in the first movie, because it allowed an audience to see me in a way that no one had before. How I Met Your Mother... I probably wouldn't have been cast in that ... had it not been for [Harold and Kumar]."

Yet not all of their adventures were big titties and humping bags of marijuana (which Kal Penn told the crowd was inspired by a scene in Raging Bull). The cast and crew were quick to stress the added backstory, the hows and whys of Harold and Kumar, like where they got their reefer madness and what they were really like in college.

"Look, you've only really spent a night with these guys, and just 'cause you've seen it thirty times doesn't mean that these guys have changed, which is, I think, the cool part about doing a sequel like this where you learn all this stuff about them," said Kal.

Everyone involved is also quick to point out that in this case, it really was the fans that made the sequel possible.

"When we wrote the first Harold and Kumar, we always wanted to make more of these movies and unfortunately when the film first came out it didn't really catch on immediately in the theaters, and we were told that we were never gonna have a chance to make another one. And luckily the fans out there supported the film on DVD and it was literally that support that gave us this opportunity. We're just so thankful to be here."
