Nursery Rhyme. CCXXIII. Riddles.

[One leg is a leg of mutton; two legs, a man; three legs, a stool; four legs, a dog.]
Two legs sat upon three legs,
With one leg in his lap;
In comes four legs,
And runs away with one leg.
Up jumps two legs,
Catches up three legs,
Throws it after four legs,
And makes him bring back one leg.
