Crabby Patties or Cool Cucumbers?

I don't think that Don and Devin were really crabby, but they sure look like it! This was last summer at the park watching a group of entertainers called Rhythmic Dogs. They were really cool. They made music out of banging on things. For the rest of the summer I was 'lucky' enough to have the kids treat me to my own private armature concert almost every day!!
