I'm going to Dragon Con this year, first time, in Atlanta.
I'm looking through the list of celebrities that will be there, and some of them have had messy scenes. Now, recognizing them as having messy scenes may not be too weird, but I can also point out the show. Some of the celebrities are:
Will Friedle, slimed on Don't Just Sit There, when he visited the set of You Can't Do that on Television
Chris Kirkpatrick: Slimed on Nickelodeon Kids Choice Awards, 1999
Joey Fatone: Slimed on Nick KCA, 1999, caked in Hanna Montana episode: Bye, bye ball.
Eddie McClintock: Slimed with purple goo on Warehouse 13, episode 2. This one was co-ed, if anyone wants to look for it.
One thing I'd like to do, given enough time, money, and resource, is create an IMSDB - an Internet Messy Scene Data Base. I think that would be awesome! See if your favorite actor ever got messy.
The database would be a great idea. Some versions already exist (the IWDB -Internet Wam/Wetlook Database, WAMTEC, WAMFLIX.com, etc.), but a comprehensive database with links to scenes would be fantastic. A lot of work, but fantastic
