If we are nimble of foot we could trip the light fantastic-- in the glow of WO'N footlights..

and nimble of foot also leads to nimble toed--

i suppose trip above really means travel, not stumble.. which you could do if you have two left feet
and the next time you see see some one stumble, you can comment "Did you have a nice trip? See you again next fall." which is only polite to say when a mishap has damaged nothing more than their dignity--since it make them laugh, and distracts them from situation.
