I was thinking about that when I saw your post a page back, Nanny. Jumped on a Toad? ;D
I think the name 'Ralwus' is pretty witty.
I wasn't very familiar with Hubpages when I made my name (I'm still learning, actually). Now that I've been browsing Hubpages more since I first signed up and looking at the forums, I'm slightly ashamed of mine, haha. It's not a real name, it's just sort of a name I came up using my mother's side of the family.
I have to say my list of coolest screen names is also pretty long. I like ... Ralwus, CennyWenny, Mark Knowles, Haunty, RooBee (the cutest!), Benjimester, and BadCo, to name a few.
