Halloween Costume Ideas?

Hey y'all!

Gull's gotta wear a Halloween costume for his obedience class in 2 weeks. You guys were very helpful with trick suggestions, so I was hoping for some more creative ideas from y'all. I really don't want to buy a store bought outfit. One thing I was thinking of was putting a pink shirt on him and tying a shoe on his back and having him go as a Piece of Gum under a Shoe. :) My friend says nobody'll know what that is though. Anyway, that's the kind of thing I'm looking for.

Thanks,
Par...
