What makes Icky Ricky so icky? Well, there was this time, for example . . .Chapter #1HOMEWORK CHEESE and THE BOOGER BUBBLE FREAKOUT    StarringTHE NOT-SO-SAFE WATERMELON BIKE HELMET!     Yesterday, Gus came over to my house and wanted to go bike riding. I couldn't find my bike helmet. So instead of wasting time looking for it, I decided to make a helmet.     I brought a watermelon from the kitchen out to the front steps. I cut it in half with a plastic knife because I'm not allowed to use real knives and that took forever. Then I scooped out all of the insides. I put the watermelon on my head. It looked really cool. I had an awesome bike helmet, even though it was all drippy and stuff. Then Gus wanted a watermelon helmet, too. So we made his from the other half of the watermelon.     We didn't know if the helmets were safe for bike riding, so we tested them. We dropped things on them, like a book, splop! And a shoe, clomp! And a wrench, blonk! And then a really big book, kasplop! Then we did one more test. We ran into a wall as hard as we could.     Wham!      Splop! The helmets cracked, and the juices and gunk ran all over our faces. We couldn't go bike riding.But all of that testing had made us hungry. We went back to the steps and scraped all of the watermelon insides into a bowl. But there were ants in it now, and a leaf and a stick. I don't eat ants. (It's not fair to them.) We let the ants have the watermelon, and we picked out the seeds.     We decided to have a watermelon seed-spitting contest.
