I could explain how we got to this point in the conversation but it's not important or interesting.
Me: Ponies are a completely different animal from Horses. They're smaller.
Dave: The weird ones are those miniature horses.
Me: (Nods head sagely at this wisdom)
Dave: What would be great is if you got a monkey and dressed it up like a cowboy and made it ride the mini horse.
Me: Like for a party or for anytime?
Dave: For anytime. Then when people came over and saw the monkey riding the horse they'd know how awesome you were.
