How does a person get spontaneous humor?

You need to be able to analyze a situation and come up with a smart remark. However it is easier to, in a way 'eat off of someone else'. By that I mean grow on a joke that was told earlier. In a way revive the humor at a later time. You need to be able to know what is going on and keep an eye on the following:

1. Jokes being told- to bring them up and grow on them at a later time.

2. Have funny friends- they help create a relaxed enviorment.

3. Always have a funny sound effect- tell a story and use funny sounds (like a high pitched car going by.)

4. NEVER laugh at your own jokes- this would suck if it wasn't funny. Laugh once they get it.

Other than that have fun ALL THE TIME!
