Eye of the Beholder

Last summer I was having lunch with Mom and Riley, and Mom declared that while she likes raisins by themselves, she detests them in other food recipes. Apparently the re-absorption of water into the shrivelled nuggets grosses her out. She explained this further, with a metaphor. She said, "It's gross, it's like...tics."

To this I pointed out the obvious and said, "...or like grapes..."

I didn't think it was that funny, but water came out of her nose.
