lorne's spell to restore cordelia's memory makes everyone think they're high school students who have been gathered to hunt a vampire: angel.
alexis denisof and david boreanaz began getting the giggles as the program progressed. it got to the point that when angel runs back into the hyperion hotel to report that there are hundreds of demons outside (he means the cars on the freeway), the two could not look at each other without dissolving into laughter. take after take was wasting the time of the crew and other actors. they decided they would simply, then, not look at each other. but between 32 and 33 minutes into the program, they had quick glances, and the viewer can watch them trying to hold in the laughter.
