Pun English jokes

Marriage is a university where men lose their bachelor's degrees and women get their master's degrees.

Note: These are two puns.

Bachlor, as a degree, is a bachelor's degree, that is, an undergraduate course. At the same time, it also means "single man";

A master's degree is a master's degree, but another meaning is "controlled" and "dominated".

So this is a very interesting little joke. Of course, men are no longer single when they get married, while women are often in charge of family affairs in marriage, even acting arbitrarily and willfully.
