Bad News Combination

The other day my friend messaged me saying, "bro I have two pieces of bad news for you." I told him to combine them. He replied with, "your girlfriend is cheating on both of us."

Explanation

The humor is based on the dark twist. The friend initially presents two separate pieces of bad news, but when combined, they form an even worse scenario: the girlfriend is cheating on both of them. It's funny because of the unexpectedness and the betrayal combined with dark humor.
