Ways to Scare Goku: 1. Cook him a nice meal, then if he asks what it was, tell him it was a fresh puffer fish. 2. Dress up as a nurse for Halloween. 3. Give him your bag of treats, then, after he's half-way through the bag, go into a long monologue about all the sickos who put poison and razor blades in the stuff. 4. Follow him around, holding a syringe. 5. Tell him there's a psychotic clown under his bed. (He'd believe it.) 6. Tell him that garden gnomes will eat him. 7. Ask him a complicated math problem. (That scares me too!) 8. Put a lobster in that oil drum he likes to bathe in. Live lobster!

Here's an easy target, with his terror of needles and all (I can sympathize O_O). Buy I won't be annoying and make an unending assortment of needle jokes.
