those are great, someone did the find x one on our whiteboard in our living room during a party. we were studying earlier that week, and they circled x in the graph and wrote "found it"
one time on a math test, I finished pretty early and didnt know how to do a problem so for a good 10 minutes I drew a tree stump, wrote Im "stumped" next to it with an arrow. Got 2 points out of it
