Depending on the audience, there are cute little plush things, Giant Microbes, which have a line of sexual transmitted diseases. If you get one for an SO, they can say, “13esq gave me chlamydia for Christmas…”

Other good joke gifts can come from any inside joke that you may have with your SO, so these are very situational. At one point, I had joked that my SO was a sugar mama because she was paying for something expensive for us. I later got her a t-shirt for a candy called Sugar Mama.

On one date, we were the only ones dining at an outside patio at a nicer Italian restaurant. We had ordered wood fire pizzas. Anyway, a very large rat came to visit the patio, and we had joked about it at the time, even naming the rat. I later gave her an ornament of a felt rat holding a pizza slice (which is apparently a thing).

I can’t think of any others right now, but I love giving little joke gifts to people along with real ones.
