Tim and Xandir, Sitting in a Tree... - S2-E11
Continuity mistake: In 'Xandir and Tim, Sitting in a Tree', "Tim" gives Xandir a gun to shoot Captain Hero - it is a cartoon version of something like a .38 revolver. Xandir leaves the room and attacks Captain Hero/Tim with an automatic, something like a Colt .45. Completely different guns.
Tim and Xandir, Sitting in a Tree... - S2-E11
Continuity mistake: When an Entertainment Weekly magazine falls onto the table and Foxxy and Clara both hold it. If you look at Foxxy's hand you see that her furry bracelets suddenly disappear and then reappear.
Answer: She was in the show 90210, so I'm guessing it's a reference to something she did in the show?
