Teaching assistant Puns

Our professor told us he had a lame excuse

He sets it on a plinth and tells the students they’re free to take a couple after class is over. Halfway through teaching the senpai or sensei’s assistant approaches and tells him he has an important phone call. He tells the class to find a partner and practice. He comes back fifteen minutes later and the plinth is knocked over, the bowl is in pieces and the wontons crushed and scattered about. He is dismayed that his students would engage in such sensei-less wonton destruction.
