My sense of humour is notoriously weird. I come from the land of Python, Son of Goons, Son of Marx (Brothers). See if this tickles in the right place.

In Mr. Williams' general stores, the kind that sells everything in a small town, a young man was hired as assistant. As it was his first day, he cleaned up and stocked shelves whilst Mr Williams dealt with the customers.
A man came into the shop, and Mr Williams said to the boy, "Selling stuff is easy, lad. Watch what I do!"
The man came up to the counter and asked for a packet of grass seed. The sun had turned his lawn into a wasteland. "Certainly, Sir," said Mr Williams, "we have the very best there is." He produced the packet of seed, but then, leaning on the counter and speaking in confidential tones, he warned,"Of course you do know what this seed can do?"
"What do you mean?" asked the man. "Well, this seed grows overnight. You'll have a new lawn in a couple of days, but you have to cut it regularly, or it will be a jungle in no time. Do have the lawnmower for the job?"
"Well, er ....."
"We have an offer this week on the most effective lawnmower you've ever seen."
Within ten minutes, Mr Williams had sold the man a lawnmower.
"You see, boy? That's how it's done."
Shortly after, a new customer, also a man, came into the store and the apprentice was given the task of dealing with him.
"Yes. Sir? What can I do for you?" So far so good.
"I'd like a packet of Tampax, please. "
"Certainly Sir. Could I interest you in a lawnmower?"
"Why on earth would I want a lawnmower?"
"Well, I thought that seeing as the weekend is ruined, you might might as well cut the grass!"
