Tell me your funniest IL (in-law) story; MIL, FIL, SIL, BIL, whatever.
SO's dad is a great guy, but he's not very affectionate. Apparently, he's never bought FMIL anything for her birthday, Mother's Day, Valentine's Day, Christmas, etc. One year, she woke up on Valentine's Day to nothing, per usual, baked herself a cake, and woke him up by throwing it ON his face...icing and all. LOL.

Re: IL stories.
My Grandfather in law lived with us while we lived up north (he was only there during the summer months). One night we found him running around in the dark in his slippers and long nightgown and a lantern and we asked what he was doing, turns out he was chasing a bear (he was 91 at the time).
Another time we were at the dump and he came back all proud of himself because he threw sand in a bears face and made it sneeze.
Same Grandfather, we drove him to Florida for the winter and we stayed with him for a while. One day while walking through the park we saw an alligator, he decided to chase it with the camera to try to get a good picture.
