The Ringmaster was a character seen in a series of eleven animated sketches on Sesame Street. He was a character very much like the ringmasters seen in most circuses. The sketches he appeared in taught children how to count numbers of various animals.
Each sketch began (and ended) with a number of red dots appearing on-screen, which then turned into whichever numeral was to be featured in the sketch. Then the numeral became part of a 3-by-4 grid of squares and flickered as it appeared.
In the Ringmaster sketches, the top-hatted character boldly announced however many animals would be performing whatever tricks. With a whip he made the animals rearrange themselves in many patterns, despite the fact that their number remained unchanged.
Additional sound effects were added to the sketches when they were rebroadcast during the 2000s.
