Deliberate mistake: Why would Al have his Polk High football uniform in England?
Suggested correction: Al cherishes his memories as a high school football player. It's quite possible that he takes the uniform with him on some trips, especially when going to another country. I've known people who do this with items that are important to them; i.e. a jewellery box or a favourite picture of family. They feel better keeping the item with them, in case something happens at home while they are away.
Deliberate mistake: When the family is trying to get money from Al at the start of the episode, he throws it on the ground making the rest of the family to dive on it and you can see Bud get it, then throw the bunch of money in the middle of Kelly, Peg and Bud so they can all get to it instead of taking it all.
