Mummy Returns, The Easter Egg - Director Cameo

This egg is in the scene where Rick O'Connell first meets Izzy. It's around the time they're discussing the eyepatch. In the background is a bathtub with a guy in it reading the newspaper and humming. This is the director, Stephen Sommers. (This is mentioned in the director commentary track on the DVD which, by the way, is really interesting compared with other commentaries I've heard. It's worth listening to.)
