Stamp Placement

Why did it take so long for drinking establishments to place those stamps indicating you're over 21 on the inside of your wrist rather than the back of your hand? I've spent the better part of my life furiously scrubbing away at ink stain blobs. The worst is when you have 2-3 of those suckers, layer upon layer that refuse to wash off the morning before the big meeting at work or worse yet, a job interview.

Never again. Stamps on the inside of your wrist effortlessly disappear! Scrub-a-dub-dub.
