I crack jokes. I mean it just happens. It’s not intentional.
However if you told me to crack a joke out of the blue, I’d say the lamest thing or the scenario below would take place.

Ms.S. : mummy, make me laugh.
Me: what do you mean, make me laugh?
Ms.S.: aree, tell me a joke.
Me: do I look like a stand-up comedian to you?

Ms.S. Bursts into loud snorting, grunting laughter, for absolutely no reason while we walk on the road to pick her brother from school. We are rushing, coz the signal will turn red any moment now.

Ms.S: you are. See, you just told me a joke.
Me: what do mean, just walk fast please, and stop grunting when you laugh. Please.

( Pulling her, so we can walk faster.)

Ms.S: (laughing uncontrollably) you are not a stand up comedian, you are a walking comedian.

While the conversation did not make sense, I chuckled, and also my chappals gave up, which was added comic timing. So I guess. I am a comedian, that’s a laughing stalk.

A stalk! geddit.
