Gallop gallop gallop

We have a little game called "gallop gallop gallop." Mike likes it WAY more than I do, but since it elicits great big, belly laughs and high, pitched giggles I tend to give in anytime he wants to play. Basically, anytime I am laying on my stomache he will come up and climb onto my back and start bouncing. This is my cue to get up and start galloping around with him on my back. While galloping I must also say "gallop gallop gallop" and jump around like a crazy person. I usually add a few "whinnies" and "neighs" in just to mix things up a bit.
