There used to be a bar/rock club in Brooklyn that was entirely themed around this. They had a huge tank set into the wall behind the bar and women in mermaid costumes would swim around in it in 15 minute shifts.

I like the one that says "You can make your own tail." I'd like one of those with a few more lines screen printed underneath: "Order your IKEA RealDoll today!"
