Trapped in a Purple Haze Easter Egg - Kid at Party

When Jonathan Jackson and Carly Pope are at the party, near the beginning of the movie, Jackson and Pope bump into a teenager wearing a green dinosaur suit. (This is the scene right before the one where Jackson and Pope go sit and talk on the roof of a building). The person in the suit, if you look closely, is Jackson's real life brother, Richard Lee Jackson, in a cameo.
