Physical change Puns

Then I can go ahead and be a physician.

Hi guys, I need to change my username online (mostly used in games) as it's not really something unique ( came from a book I read when I was younger ).

I'm trying to find something quite funny, with plays on words for example. But english isn't my native language and I find it quite hard ! So I'm asking you guys to help me :) You're the best for that imho !

If you could help me find something mixing music (percussions/drums), sciences (my field of study, physics to be more precise), beer and animals maybe (?) (because I like that !)

I think this is possible to find something using some science-specific noun and something else. But I can't seem to find one that suits me :(
