Why that Nun didn't like Virgin Mary?
Because she was straight into Jesus.
Nun and Virgin Mary
Explanation

Listen here, genius. You probably think that religion is boring, but jokes about nuns can be funny. This joke is funny because it uses the word "straight" in two ways. It means that Mary was directly involved with Jesus, but it also implies that Mary was heterosexual. It's funny because nuns don't like when people are straight. Get it?
Haha
Mary probably got fucked by Jesus
