I love Jack Handey's humor.  I don't even know how to describe it, it's just so off-the-wall.  But it gets me to laugh nearly every time.  Here's a sample:

The face of a child can say it all, especially the mouth part of the face.

If a kid asks where rain comes from, I think a cute thing to tell him is “God is crying.” And if he asks why God is crying, another cute thing to tell him is “Probably because of something you did.”

If you’re in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins. Maybe it’ll make everyone think how stupid war is, and while they are thinking, you can throw a real grenade at them.

Before you criticize someone, you should walk a mile in their shoes. That way, when you criticize them, you’re a mile away and you have their shoes.

Anytime I see something screech across a room and latch onto someone's neck, and the guy screams and tries to get it off, I have to laugh, because what is that thing.

To me, clowns aren't funny. In fact, they're kind of scary. I've wondered where this started and I think it goes back to the time I went to the circus, and a clown killed my dad.

And my personal favorite:

One thing kids like is to be tricked. For instance, I was going to take my little nephew to DisneyLand, but instead I drove him to an old burned-out warehouse. “Oh, no,” I said, “DisneyLand burned down.” He cried and cried, but I think that deep down he thought it was a pretty good joke. I started to drive over to the real DisneyLand, but it was getting pretty late.

So the challenge here: try to make your own Jack Handey-style Deep Thoughts.  Write your own little anecdotes, and try to get as many LOLs (or ALLOLs) as possible!
