I agree completely, byb. I was amused to find this in OED:

mumble-the-peg {I guess we must have mumbled this}
Now U.S.

A boys' game in which each player in turn throws a knife from a series of positions, continuing until he fails to make the blade stick in the ground. Hence mumblety-pegging vbl. n.
The unsuccessful player is compelled to draw out of the ground with his teeth a peg which the others have driven in with a certain number of blows with the handle of the knife. In Antrim the game is said to have been played with a fork instead of a knife (see E.D.D.). In Scotland it is locally called ‘knifie’.
