I have been checking out IMDB.com online to see what other shows the cast of Greek has been on and I ran across this gem.
The funniest part is Professor Segal (Josh Randall) is in this episode too.
Scott’s name is in the credits at 5.15 in Professor Segal can be seen here too. 6.13 in. I knew I recognized the name at the start of the credits.
This same link has Scott at 12.00 minutes in. At 13.08 he speaks.
At 20.13 Scott’s character gets mentioned.
This link is different from the one above but it is a shorter version of the first video and has Scott’s part (at least some of it)
Break down of first video with whole episode
5.15 : Scott Michael Foster’s name in credits
6.13: Josh Randall (Professor Segal)
12.00: First scene of Scott’s
20.13: Characters name mentioned.
