Any ideas for fun things for adults that I can put in christmas crackers?

Yes i’m an adult and i love christmas crackers! It’s always fun to see what you get, even if it’s crap.

So anyway, instead of buying those cheap crackers where you just get crap, this year i want to make crackers for everybody.

I’m using toilet paper rolls (i assume they’re the same size all over the world), and so far all i know what i want to put in there is a chocolate truffle.

So, have any ideas of other interesting thingies i can put in there (that are small enough to fit)?
