In the opening before the gun fight cliff, Wendy and Joe are dirty and disheveled, however during the gun fight flashback they are well groomed and clean.
During the last flashback, Spab is seen pulling out an Uzi that he had never acquired.
At the end the reporters are talking about how the girl that shot Wendy and Spab was exercising her 1st amendment rights. The 1st amendment gives you the right to free speech, not the right to shoot someone.
When Monica kisses Cliff in the kitchen, his cigarette is no more than two inches long. When he turns to sit down, it is now almost full length.
