This line from the brawler description jumped out at me today:
Quote:
At 1st level, a brawler gains Improved Unarmed Strike as a bonus feat. A brawler may attack with fists, elbows, knees, and feet. This means that a brawler may make unarmed strikes with her hands full.
I immediately imagined a multiclass bard/brawler using Inspire Courage .... with a set of bagpipes. He manages to continuously play the bagpipes while striking enemies with his knees and feet.
This also works for Full-Contact Clogging.
