Appendage...

A boastful, big bully, Did not understand fully The naked truth, When forsooth, His pants got caught in a pulley! There followed ear-bendage... And linguistic horrendage! As his trews dropped... Out of them popped A miniscule appendage! The moral of story, Of tale somewhat gory: Bear in mind, one and all, There may be a shortfall, In what you perceive as your glory!
