When on a date women love to laugh and enjoy a man with a good sense of humor. By all means if you know some good jokes, share them with your date. It will make a real good impression on them and they will think of you as a guy that's a lot of fun to be around.
I must warn you though, if you don't know the woman very well I would stay away from offensive jokes. She might be offended and could even cause her not to want another date with you. So, in my opinion you are better off telling clean jokes and not too suggestive.
What if you don't know any good jokes? That's no problem. Go to your local book store or fun shop and they will have some good joke books. Another idea is to find jokes on the internet. Just simply do a search with your favorite search engine. You will find tons of good jokes that way. Then, you can practice these jokes on your friends before you try them out on your dates.
P.S. Please whatever you do, don't tell bad jokes. You need to make her laugh and if you tell crummy jokes you may bore her to death. Also, some Men's publications have a section featuring some good jokes. And if you go to comedy clubs try and remember some good jokes that the comedians tell. If the audience is dying laughing, then it's a good bet that when you tell the same joke to your date, she will think you're funny and admire your sense of humor.
