My son likes to play with my daughter's Barbie car and jeep. He puts a Barbie or two in them and then races around the house really fast.
This morning he was racing around with the car and sneezed on it which of course GROSSED my daughter out completely. After he sneezed he wiped off the car and proudly announced he cleaned it and it was "good as new."
As you can probably guess, I don't think my daughter agreed with him. :-)
