maybe I'm gonna present you few examples of such kind of jokes to give you a hint what I mean.
-Alan you remind me of a sea.
-So, you think I'm romantic and wild?
-No, it's because you make me sick.
And the second one:
Boy: Angela, since I met you I can't eat, I can't drink...
Girl: Is it because you love me so much?
Boy: No, it's because I have no money left.
