Plot hole: Throughout the show it is reported several times that Billy and Ally met when they were both eight years old in a park by sniffing each other's bottoms. However, when Billy is buried in season 3 his tombstone reads, 1968-2000, making him 32 years old. Ally is only 29 and does not turn 30 until later in that season which would at the very least, put them 2 years apart. (00:41:15)

Plot hole: In the previous episode, when Jimmy offers to apologise to everyone about stealing money to pay back gambling debts, Eugene tells him not to, since if the other firm members found out they'd be obligated to report the theft, which could endanger the firm. This episode, Eugene justifies reporting Jimmy to the bar for saving the boy's life against the client's orders by shouting about Jimmy's gambling theft in front of all the firm members whom he previously said he didn't want to know about it.
