Back in my long-ago drinking days we used the following rhyme:

Starkle, starkle, little twink.
Who the hell you are, I think?
I am not under the alkifluence of inkihol
As some thinkle seem to peep I am!

If you could recite this, you could have another drink. Inability to get through the dreaded "Starkle, Starkle" meant that you were cut off.
