I'm going to make a bad joke
Is there anything else that you would like to let me know of?
No I just want to make someone laugh.
That's neat you just want to make people laugh, go for it! It's your incentive to make jokes and let people be happy. You are good for wanting people to feel better rather than not.
I just want someone to laugh, not be the next guru or something.
Making jokes is ok as long as they are not at the expense of someone else. Getting other people to laugh can be great as it can make that person more happy.
