Balancing act

It's kind of lengthy, but I'd caption this:

"All the one-legged girls formed a clique, started dressing alike, and leaned on one another for support."

I'd go for humor since we tend to look at legs in pairs and the "pairs" here jangle the senses since they don't match (other than being all 'lefties'). I'd even think about cropping it down to the very bottoms of the skirts just to heighten the effect, but then the caption loses something.
