Considering that I work in marketing, I have absolutely no ability to retain names. This translates to a lot of awkward social events (You know: "Hi...you!"), and a lot of me pointing at the television screen and shouting, "Hey! It's that guy!" when I recognize someone's face but cannot put it to a name.
This happened last night while watching the "Crisp" episode (ep 1x2) of How To Make It In America. Thanks to IMDB, I now know that it was Griffin Dunne who guest starred as Ben Epstein's former professor. Griffin has worked steadily since 1975 (and is a lead character on the show Trust Me), but I remembered him from the Macaulay-Culkin-bee-stinger known as My Girl.
