Empty your bladder before you do your nails

Unless you intend to

a) smear the coats of of polish you've so painstakingly applied to perfection while fumbling to unhook/unfasten/pull down your gear.

b) go nekkid the entire time the manicure takes to dry. (HAVE YOU NO SHAME?)

c) remain bottomless after doing the deed.

P/s: The thumbs always get it bad.
