I love cameos in movies. Especially John Landis movies in the 80s. He used to put his film director buddies in his films all the time. Spies Like Us had Joel and Ethan Cohen. Also Sam Raimi, Costa Gavras, Michael Apted, Larry Cohen and Marty Brest. And Into the Night had tons of director cameos: David Cronenberg, Jonathan Demme, Jim Henson, Jonathan Lynne, Paul Bartel, Paul Mazursky, and Amy Heckerling. Speaking of Amy she put her boyfriend Martin Brest in a cameo in Fast Times at Ridgemont High. Feel free to add more. Yeah I love cameos that is my confession.
