What if I want to dance naked? Of course I wouldn't need a tick check as an excuse, but having an audience is always nice.
Speaking of which - following summer field training in my Army days we were actually encouraged to check each other for ticks in the showers. And you'd ask guys to spread their cheeks, because ticks like to go in skin folds.
If you found any then some guys would dress and go directly to the troop clinic to have them removed, with an entry put into their medical record. Others were content to have a buddy remove them with tweezers.
I tried to avoid giving these naked ass checks to other soldiers because I'd start to get a hardon. I guess the lowly tick does have a nobler purpose.
