First dates should, first and foremost, be fun. If you're not having fun, it's not a good date. This goes for both you and your date.
Yes, you should be getting to know one another. A bit. But that's not the most important thing.
It won't matter that you learned everything there is to know about your date's hometown, family and profession if she/he was bored all night. Boring dates don't tend to lead to second dates. Fun dates do.
That said, sometimes it can be helpful to think of a funny story (a short, amusing story) to have ready to share in case there is a lull in the conversation. Perhaps it's a funny thing happened to me on the way to work the other day type of story. Or something like, I was cleaning my home and found an album of pictures from high school. I can't believe how ridiculous we all looked.... Maybe not laugh out loud funny, but amusing. Something light and cheerful that can be extended into a longer conversation.
