Scilly, you should only get the jokes when you pull the cracker for someone else. When you pull your own cracker (with someone else's help), you get an item and they get the joke.
With ones I've bought myself I got a fortune cookie & Glitch game from the toy vendor in Bortola, essence of rubeweed & silvertongue from ones bought in Wintry Place, & charades potion & a pair of dice from ones bought in Kalavana.
I also got a camera, & very stinky cheese in ones I was gifted.
