(S18E15) Seriously, what is it with Grandpa Simpson falling for Marge's family members? In season five he almost marries her mother, and last night he puts the moves on Selma. Talk about a lot of weird Thanksgivings.

This episode had some good laughs, but overall I wasn't too impressed. The secondary story involving Bart and Lisa building a gigantic castle out of cardboard boxes from ASS --which stood for "American Shipping Services," and is not, as one truck indicates, affiliated with the human ass-- and fighting an apocalyptic battle with the men in brown was more entertaining than the main story, in my opinion.
