I LOVE this thread. I haven't laughed so hard in ages. Thank you DCUM community! My contributions aren't particularly funny, but here goes:
My MIL has given me and DH a single paring knife (it was actually quite awesome, and we ended up buying more of the $6 knives on amazon). MIL makes AMAZING quilts. She asked me at least three times via email what colors I would like. I responded every.single.time, with the same colors. The fourth time she asked I asked my fiance (now DH) to please talk with her. I didn't know what else to do. She used completely different colors. I guess she didn't like the colors I like? We've received plenty of used books as gifts also, though I no longer think this is strange - they're perfectly legible.
Before I was married, my mom would give me gifts for my future children. She had other grandchildren, so would buy an extra set of board books, or what have you, when she picked one up for a grand child. My mom also asked each year to pick out pajamas that she can buy for me and DH to open on Christmas eve. I understand her wanting to do this for our kids. They grow and need new pajamas anyway. DH and I don't need new plaid flannel PJs every year.
I wonder what odd presents I'll end up giving someday....
