Yes, you see, it's like cricket...actually, it's not very much like cricket at all. Except it involves a ball, which is actually a dinner roll, which you fling at a dining companion who is prepared with some sort of bat, usually something found about the premises, like a soup ladle. And the chap with the bat tries to hit the dinner roll back to the chap who threw said dinner roll.

It's all great fun. [He sways a bit.]

Right-o, notes! Allow me to write you some.

[And he takes a napkin from nearby and scribbles down things like "the melody goes uppish a bit at this part and then down a great deal and then ends somewhere in the middle"]

There you are.
