When I went for my yearly physical, my toenails were painted. Not bright red, just a white pearlish color. What I didn't realize is that I had to take my shoes and socks off. The doctor noticed my painted toenails and asked if my daughter painted them. I told him that my wife and I got frisky the other night. He didn't want to go into details. I was tempted to say it was my daughter but I figured it would be easy for my wife to back me up than my daughter.
It turns out something similar happened to him - he went for a physical the day after his daughter painted his toenails bright red.
