A good reason to end up in a float is looking exceptionally
good. Some floats feature muscled boys in revealing suits, and
girls in bikinis covered in glitter. The bodies are shaped by
hours at the gym, possibly a helpful hand of a good plastic
surgeon. Going topless is OK, but complete nudity is not allowed.
Doing the samba exceptionally well is a big plus. The guys pushing
the float usually come in costumes that complement whatever the
floatees are wearing. When there's a quick stop they join the fun,
and dance and sing, too.
