We did a tandem ride one Halloween, with costumes required! DH and I went as a bear and a moose. Another couple went as a two-headed cow (this was funny - she wanted one head, but he told her she needed to be able to see!), another couple dressed as two pirates, complete with parrot on the shoulder, and the other couple was good and evil. It was a blast!

I've also done a Pipi-Longstocking costume, and DH and I were ninja turtles one year as well.

But I LOVE gnat's costume!
