Little Johnny's preschool class went on a field trip to the fire station. The fireman giving the presentation held up a smoke detector and asked: "Does anyone know what this is?"
Little Johnny's hand shot up and he said: "That's how Mommy knows supper is ready!"
A man goes to a fancy costume party wearing only a glass jar on his dick. A woman asks, "So what are you?" He tells her, "I'm a fireman." "But you're only wearing a glass jar" she replies.
"Exactly! In an emergency, break glass, pull knob, and I'll come as fast as I can!"
A daughter asks her mother, "How many different kinds of dicks are there?”
The mother smiles and says, “Well, dear, a man goes through three phases in his life. In his 20s, his dick is like an oak tree, mighty and hard. In his 30s and 40s, it’s like a birch, flexible but reliable. After his 50s, it’s like a Christmas tree.”
“A Christmas tree?” the daughter asks. “Yes, dead from the root up and the balls are just for decoration.”
