The other day we were trying to remember an old riddle that
G'ma Opal used to tell.  I never could remember how it went,
so I googled it.

I think G'ma changed the name from Twitchett to something else...
but I can't remember what it was.

So,...here's the riddle.  Guess it, if you can.

Old mother Twitchett has but one eye,
And a long tail which she can let fly,
And every time she goes over a gap,
She leaves a bit of her tail in a trap.
