I like the pear flavored ones.
One Halloween a few years ago, I set out a candy dish full of the Bertie Bott's jellybeans, and told everyone but one of our male friends. It was hysterical. He dipped into the dish a few times before he hit a bad one. He made a face, waited a few minutes and tried again. He got a few more okay ones and then another nasty one. This went on for a few minutes until he finally hit a really terrible one and had a really bad reaction when everyone finally couldn't take it anymore and burst out laughing. He said..."There's something wrong with those jellybeans."
We finally told him, and he was a really good sport. Then we had to get out the box and have everyone take turns sampling the nasty ones. The sardine, dirt, and vomit were HORRID. The grass one was just weird.
