This is a container clue - one word or set of letters goes inside another word. Look for an indicator that suggests something being put within something else.
"in" is the container indicator. You need to put AND (a joiner/connecting word) inside a word meaning "funny" that has been reversed ("comeback" suggests reversal).
Answer: LANDLORD | AND (joiner) goes inside DROLL (funny) reversed to become LLORD, giving L-AND-LORD
