Angel Easter Egg - Alien: Resurrection Reference

In the episode "Fredless," Fred's naive parents show up for a visit. After the whole gang, Fred's parents included, fight some giant bug-monster, Fred's mom and Cordelia are talking. In an effort to appear somewhat unfazed by what had just happened, Fred's Mom tells Cordelia how much Fred's dad loves all those horror movies, and that he's an especially big fan of the Alien movies - "except for that last one, he slept through most of it." Well, "Angel" series creator, Joss Whedon wrote the screenplay for "that last one," which was "Alien: Resurrection."
