Billy's tombstone reads 1968-2000. Since Ally often spoke of the time when they were both 8, this can't be true: Ally turns 30 a few episodes after this one.
Continuity error: While Ally is trying to give Billy CPR, the scarf she just removed is clearly visible hanging from her neck.
During his summation, Billy mentions Who Wants to Marry a Millionaire which aired a few months before this episode. But his tumor has him so confused, he actually had to confirm with Ally that the show actually aired.
Ally: A brain-tumor?
Ally: In... your head?
Billy: No it's in my ass Ally!
