Of course there's always the challenge recitations.

The challenger gives first one line and then two and then three and so forth, and the challenged tries to repeat them back each time.

One of the most famous goes:

One hen

Two ducks

Three squawking geese

Four Limerick oysters

Five corpulent porpoises

Six pairs of Don Alverzo's tweezers

Seven thousand Macedonians in full battle array

Eight brass monkeys from the ancient sacred crypts of Egypt

Nine old men on roller skates with a distinct tendency towards procrastination and sloth

Ten lyrical spherical diabolical denizens of the deep who all stall around the corner of the quo, the quay, and the quivvy.
