How can you make your girlfriend laugh?

Answer 1

Be funny, make jokes, be sweet to her.

Smile big, tell good jokes, but try to make it natural. She won't find it even mildly funny if your obviously trying to find a good time to put a joke into the conversation. Commenting on the world around you, without making it too offensive, can also be funny. If you are really desperate though, tickling her will work.

(for advice on tickling, go to a separate page).

Answer 2

A good sense of humor can do the trick cos gals love it when they bellies are tickled.
