Do have a group theme costume or something?

Nope, we don't.  WE just go as who we wanna (one year zombie, next 2 years Goku, last year Viewtiful Joe casual)
my friend almost always goes as some version of Link.

I personally take the easy way out...I work for the phone comapny so I just go as a phone man!  ROFL

Plus it is usually because i have to take my kids ouot right after work so I don't have time to change!
