Adult jokes-Terrific smell

Harry went into a nightclub and saw a gorgeous honey sitting by herself at the bar, so he asked her to dance.
She agreed and they took to the dance floor for a slow one. While they were cheek to cheek, Harry said, “You really smell terrific. What’s that you have on?”
The flattered girl told him it was Channel #5.
Then wanting to return the compliment, she said, “You smell good, too. What is it that you have on?”
Honest Harry replied: “Well, I’ve got a hard on, but I didn’t think you could smell it.”
