The moment when Adam kisses Corri and then she suddenly goes back in for a second kiss because she is confused and caught up in the moment was ad-libbed by Corri English and not planned or written in the script.
In the "gum scene" where the cast passes a chewed piece of gum through all four cast members mouths within the scene, they really did pass the same piece of watermelon flavored gum back and forth. All four cast members cited this as one of the most disgusting things they've ever taken part in.
The moment where Adam spits his gum directly into Corri's mouth was ad-libbed at the last second. If you watch closely you can see Corri English start to realize "oh my God, he's going to spit it into my mouth." The gag worked on the first try.
On the flyer that Lance gives Adam, his Van Halen cover band is called "Diver Down." For the digital single which was later issued for "Love it Down Your Throat" the spelling was changed to "Dyver."
