So it may have been a flop at the box offices, but “Wet Hot American Summer” has gained a cult following to be admired. Part of the appeal is Rudd’s performance as Andy, an obnoxious jean shorts and knee socks-wearing counselor at Camp Firewood in 1981. Viewers, be warned: You’ll find it hard to erase the images of Rudd’s sloppy, tongue-heavy French kisses with characters Katie (Marguerite Moreau) and Lindsay (Elizabeth Banks) from your mind!
