Why a duck?

[JennyOmanHill]

Re: I get it, I get it!

Now that I understand "duck" to be synonymous with "The likes of Jenny in a hot tub." it's all much clearer. I like ducks, too. It does sometimes take a while for the lit collective to lend insight, but I've learned something very useful today.
Next question:
Which way to the hot tub?

Let's see, I think it's just a few doors away, LukkyKnight.

There's a lot of us "ducks" floating around the tub lately; seems to be a very popular toy, right Perky?
