This year for Halloween, the boys elected to be Star Wars characters.
Alex will be Jango Fett, and Ryan will be his son, Boba Fett. Two bounty hunters, off to trick and treat for bounty. Alex came up with the idea, and got Ryan to go along with it. Jango Fett has the much cooler costume, so I wasn't sure that would fly. But Alex can be pretty persuasive, and managed to get Ryan to think HE came up with the idea. What can I say? Some days he takes after Daddy and looks like he'll be an engineer, other days he is all my son.
We had a Star Wars Halloween last year, as well.
Ryan was Commander Rex (from the animated Clone Wars tv show) and Alex was Young Anakin (also from the Clone Wars tv show).
And moving back in time, we've had:
2007: The Knight and the Dragon
2004: The Itsy Bitsy Spider
2003: My Baby Bat
