Oswald mentions having a "kid brother" in this episode, but in later seasons he is shown as an only child.
At the end, when Lewis gets out the caterpillar, they act like it's mounting the french fry (which is seen in a close up). But in the wide shots of the table we can see the caterpillar move away from the french fry.
You can't go to jail for sexual harassment--sexual harassment is in civil law, not criminal. Also, the one suing is not called the prosecution (again, that's criminal), but the plaintiff.
Drew is wearing a dark suit when he handcuffs himself to Kate at the store, but when they arrive at the Warsaw for the "wedding," he is wearing a powder blue tux.
Some of Drew's lines are also used in his stand-up comedy act such as his bit about his high-school reunion.
The picture of Drew's house appears to have a door in the front, however actually in MANY MANY shots, it shows there is a wall with coats and hats directly outside the door, and that his front door faces to the side of the house.
Drew said Mimi looked like something his nephew drew, but Drew's first nephew, King Gus (ironically Mimi's son), wasn't born until a much later season.
