A bunch of my Boy Scout friends and I play this with newcomers. You basically have to figure out if something’s a rose or not. Here’s an example:
If a rose is a rose, is it a rose? (Correct answer is no).
Listen, if that’s not a rose, and a rose is a rose, is a rose a rose? Yes it is.
Have fun driving yourselves crazy trying to figure out what makes it a rose. Anything could be an example.
(Is my yoyo a rose? No).
