The ultimate metre filler occurred to me yesterday evening.
I don't know if the old Cockney/Music hall song,"Knees up Mother Brown" is known in the US, but it goes like this:-

"Knees up Mother Brown, Knees up Mother Brown,
Under the table you must go,
E.I.E.I.E.I.O*
If I catch you bending, I'll saw your legs right off**
So knees up, knees up, dont' get the breeze up,
Knees up Mother Brown- Oi!***"

Footnotes:-
*A whole line of metre filler!
** Casual violence is a part of the local customs!"
*** Illustrating Doug's point!

Cheers
Dave
