Not sure about the joke. If it’s — here’s a guy who has “permanently” tatted himself (literal permanence) trying to weigh the “permanence” of education (abstract/metaphysical permanence) in terms of regretting the change — it’s not the usual witty/cleverness of WuMo.
My sister had a cat she would keep out on the screened in porch. When Thumper wanted in, he would jump up and have two paws on the door knob. Then he would start swinging, and -crazy- he got the door open. (Maybe he was a cat burglar?)
Well done!
