When I was trying to decide where to post about meeting them, I did see that thread. I just decided decided it would be good to start a new thread. At the time I skimmed the thread you mention, but what Noonchester said did not sink it. Now it has. That is awesome that he met with him and everything. I would agree with his assessment that Dave is a quiet man but very willing to answer questions. Steve was much more talkative.

I wish Noonchester would post more and tell us about himself and how he got that job and what he does. Hint, hint. I notice on his profile he lists his occupation as actor. I would like to know more
I have some more links to some great videos. The first is at Google video. There are four parts because in total it is about 30 minutes long. It was filmed Sunday afternoon and Bunsen Honeydew is in really rare form. Someone said he wasn't all that funny, but in this performance he got a lot of laughs and there was a huge crowd.

The other three parts are there. You just have to look on the right side for them.
The other video is on LaughingPlace.com. Interestingly enough there is a crossover between the video on google and this one. The person on google actually filmed Doug interviewing Bunsen (Video Part 3) and then on LaughingPlace you can see the interview! It is pretty cool.

You have to go about half way down to get to the video links.
