Toilet Surprises

I've been finding odd things in the toilet lately. This is not about poop, so don't worry. My 22 month old son "G" has a new fascination with sticking things in the toilet: Q-Tips, dinosaurs, mega-blocks, rubber duckies, you name it. I think he likes the 'plop' sound it makes. Who wouldn't? I don't think I'd mind so much if I didn't have to reach in and grab it. It's not as if the toilet is really dirty (I clean it regularly), it's just that it's the toilet.  I don't know what to do to make him stop. I've told him that putting things in the toilet is yucky. He says, "Yucky," and then a couple hours later I open the toilet lid and surprise, there's another 20 Q-Tips in the toilet. I guess I'm just going to have to keep some extra disinfectant around.
