Bingo is also the name of a children's song about a dog. It goes like this:

There was a farmer had a dog and Bingo was his name, O!
B, I, N, G, O,
B, I, N, G, O,
B, I, N, G, O,
and Bingo was his name, O!

You repeat the song six times, and each time through, you replace one of the letters in the chorus with a clap. So the second chorus is:

{clap}, I, N, G, O,
{clap}, I, N, G, O,
{clap}, I, N, G, O,
and Bingo was his name, O!

..while the very last chorus is:

{clap},{clap},{clap},{clap},{clap},
{clap},{clap},{clap},{clap},{clap},
{clap},{clap},{clap},{clap},{clap},
and Bingo was his name, O!

If you have a very excitable and easily amused group of preschoolers and wish to stretch the song out until naptime, you can continue from there and add the spoken letters back in until you're back at the first verse.
