Oh, that takes me back.
Gentlemen, please! There’s only one way we can solve this for sure…
We must find, capture, and dissect a mermaid to examine it’s musculature and skeletal structure. Actually, we should make that several mermaids, to compare against each other. (I’d hate to find out, years later, that the only one we bothered to catch was just a freak or something.)
::silence, crickets::
Oh fine, sure, be like that. You know, that’s the same sniveling anti-science attitude that killed my Unicorn vivisection research. I hope you’re happy.
Some do. Ever see Bette Midler in Divine Madness?
No one would ever admit to finding such a beastie. 
Okay, she’s half-woman/half-porpoise. Happy now?
- Mermaids are mammals.
- Mermaids fight ALL the time.
- The purpose of the mermaid is to flip out and kill people.
Just like that time when he talked about mermaids having knees.
And the time I fought the Giant Chicken.
Considering what they’ll probably be doing out of water I imagine the knees come in quite handy.
I wonder if the term “mermaid” brings up more bad art in an image search then any other term.
Dead heat with “unicorn”, I betcha.
You’d have to go some to beat this one, though. But at least it answers my mermaid/ass question.
Speaking of things mermaids don’t have, my all time favourite Aussie slang term is mermaid. Truckies used to use it for transport inspectors who set up temporary weighing stations to ensure that trucks weren’t overloaded. They were called mermaids because they were useless cunts with scales.
That ain’t a Mermaid!
That’s a typical resident of Innsmouth, Mass. 
They’ve tried to have asses, but the donkey keeps drowning.
Do mermaids have vaginas?
I mean, where to baby mermaids come from or is it just a lesbian fish community that spontaneously reproduce?
As long as actresses insist on having knees, so will mermaids depicted by them.
In art, mermaids vasry. Really old prints often show mermaids with split tails. One Playboy cartoon from the 1970s showed a mermaid whose tail began at the top of her legs, giving her both a vagina and an ass.
In Jack Chalker’s G.O.D. series, the mermaid has a porpoise tail, with horizontal flukes and no scales. One erotic cartoonist depicts mermaids with removable tails, with knees (and vaginas and ass) underneath.
They’re imaginary creatures. You’re only limited by your imagination.
In the Museum am Markt in Karlsruhe Germany there is a two tailed mermaid who doesn’t get scaley until just below the knees.
God I hope not.
The mermaid in Copenhagen has knees. I’d regard that is definitive.
Their fish tails turn into human legs, perfectly capable of human-style reproduction, when dry. What, you never saw that mermaid documentary, “Splash”?
Kind of like grunion?. That must be something to see!
Daryl Hannah’s legs are [definitely something to see.
Swim, Ariel! Swim for your life!
