In search of a new shower for our home, my wife and I went to a bathroom-supply store.
We discussed our needs with a young saleswoman. Since it was near closing time, we had to curtail our discussion and made plans to come back the next day to make our final decision.
Later that evening, my wife and I were at a restaurant, where the same young lady from the bathroom-supply store was now working a shift as a waitress.
As she passed our table, she suddenly recognized us and called to me in a loud voice, "HEY! You're the man who needs a shower!"
A fishmonger is painting "FRESH FISH SOLD HERE" above his door when a passerby comes to meet him. "It's probably not necessary to write, 'Here'; you're not selling it anywhere else after all."
"No, that's right." the fishmonger replies.
"And it's probably not necessary to write 'Sold' either, since you wouldn't be giving it away."
"No, that's true," the fishmonger says.
"It's probably also not necessary to write 'Fresh' as your sellers naturally will assume it is fresh," the helpful man continues.
"Yes, that's quite true," the fishmonger replies. "Thank you very much, you've saved me a lot of trouble."
"You're welcome," the man replies. "Oh, and by the way, you probably don't even need to write 'Fish'; I could smell it from a block away."
