Howdy, hopefully this is allowed, the other servers seemed more strict and this seeeeeeemed the best place + flair?
I am going to decorate my brother's graduation cap since I don't know if I can attend his graduation itself.

I however, am a chemistry grad student and he is a mechanical engineering student, who is very good (from what i can tell) at modeling parts and machining them.
I do not know any of the insider engineering jokes, and so far think the google results are either outdated or just not that fun?

What jokes do yall have or what engineering-specific 2d patterns do you think could work?
I'll honestly take just about anything as a suggestion to start
Thank you!
