Be careful what you ask for..you might get the opposite..

..For some reason, I neglected to charge the rechargeable batteries this morning and was left without a fresh one for my wireless microphone right as spin class was to begin.  I think fatigue is getting the better of me.  I managed to connect the back up microphone in time to salvage most of the class, but I was never really in to it.  I hope they managed to get a good workout in any case.
