A guy and a girl meet at a bar. They get along so well that they decide to go to the girl's place.
A few drinks later, the guy takes off his shirt and then washes his hands.
He then takes off his trousers and washes his hands again.
The girl has been watching him and says, "You must be a dentist."
The guy, surprised, says "Yes! How did you figure that out?"
"Easy," she replied, "you keep washing your hands."
One thing led to another and they make love.
After they have done, the girl says, "You must be a really good dentist."
The guy, now with a boosted ego says, "Sure, I'm a really good dentist, How did you figure THAT out?"
"Didn't feel a thing!"
How do you know you are a Master Gardener? There is a decorative compost container on your kitchen counter. You would rather go to a nursery to shop than a clothing store. You prefer gardening to watching television. You plan vacation trips to arboretums and public parks. Dirt under your fingernails and calloused palms are matters of pride.
