I've had my share of "timbers" while riding outside but it was while I was teaching an indoor cycling class that really made me appreciate embarrassment. My cleats had gotten a little loose without me noticing and I had clipped in, ready to lead a class on an imaginary journey when, about ten minutes into the "journey", I saw something that needed my attention (could of been a member with a bad set-up or someone needing a towel) but anyway, I couldn't clip out. I was twisting my foot like I was double jointed but for the life of me, I couldn't get loose. Finally, I just released my foot from my shoe and did what I needed to do and mentioned (since I was mic'd and cueing) I had a little "technical difficulty" I proceeded to remount the bike, get into the shoe and continue the class.
At the end of class all I could do was...get my foot out of my shoe...go to the front desk and ask where the hex screwdrivers were...and go back and retrieve my shoe.
Vertically challenged, but expanding my horizons.
