After Duffy's "injury" while he is lying on a bed, Phil and the rest of the cast bring Duffy's "magic collar" to him. Phil is wearing a plaid shirt with short, plaid sleeves. In the shot where Phil is putting Duffy's collar on him, his shirt sleeve is that of a decorative Hawaiian shirt, but in the very next shot, Phil is wearing his original plaid shirt.
Tina reads a webpage that says Phil sold his company to something called GlobeTech, but further down the same webpage, it says the company's name is "Globel Tech" - now two words, with the word "global" misspelled.
Susan reaches into an oven that just finished baking the cheese puffs with her bare hands and takes the pan out and doesn't burn herself. Then, minutes later, Phil takes the pan out of her hands and it burns him.
