A man goes into a sportwear shop, and when a pretty blonde assistant asks him what he wants, he goes red in the face and stammers, “A packet of condoms, please.”
The assistant says, “This is a sportwear shop, we don’t sell condoms!” and the man leaves.
Two days later, he’s back. “A packet of condoms, please.” “I’ve told you before, we don’t sell condoms!” and again, he gets all flustered and leaves hurriedly.
Three days later, and he enters the shop again. This time, the manager is ready for him, and goes up to him, saying, “We do NOT sell condoms!” He blusters, and eventually admits, “Actually, I’m after a Dallas Cowboys shirt, but I was just too embarrassed to ask for one!”
