Which would you rather have?: 1. Portal gun 2. melon blaster 3. cat canon 4. Psychics gun 5. assassin blade (i personally want a psy gun)

1. It'd be cool to have a portal gun.
2. I'm allergic to watermelons so that won't be good for me
3. I don't want to be firing adorable cats at anything unless myself.
4. That'd make moving heavy things easier.
5. I'd most likely get arrested because I'd use it on people who I hated.
All in all, I'd most likely go for either the Portal gun or the Physics Gun.
