there could be some funny iterations of the handle that one can come up with.
Nothing funny with RodTidwell itself. But how about, Rod Tardwell, Rod Turdwell, Todd Lardwell, Lord Sadwell
Nothing funny with GaGambler, but how about GaGambersSmarterBrother, GaGamblersRetardedBrother
Nothing funny with inicky46, but how about inooky etc
Nothing funny with lungman, but how about dungman, Dungie, Dungie Dungbeetle
Nothing funny wit UDO, but how about UDOLT, UNDONT
Nothing funny with FIDCUOF, but how about FIDIOT. (I could tell you one more that I came up with, but last time I posted it, it got my ass moderated for 15 days)

Most of the ones on your list were invented by yours truly, though I assume you meant "Udolt" when you wrote "Udoit."
PS: I didn't invent FIDIOT and don't recall who did. I don't think I coined Dungman but did start The Dungbeetle. Nor did I invent GaGamblersSmarterBrother (that was his alias when he modded here), but did own GaGamblersRetardedBrother and inooky46. The latter was pre-emptive so no one else could use it, along with inicky46sMother, Sister, etc.
You're Welcome!
Oh, and I'll take credit for Tardwell and Turdwell, too.
I stand corrected. I was under the impression that it was UDOIT, so it wasn't error in typing, probably error in remembering what it was.
I can't talk openly what the other one for FID was, and I invented FIDIOT as I did the other one.
Dungman was GaG written all over it. I don't know who did Dungbeetle.
I own the rights for Todd Lardwell and Lord Sadwell.
I am surprised nothing funny has come out of my handle yet. Something lame like CurlyFries (Cosette) and CurlyQ (CPA), neither of which are remotely funny.
