Joe and Mark are sitting in a pub.
Joe says to Mark, “Every time I see you in here you walk out with a different girl. What’s your secret?”
Mark replies, “It’s really easy. As soon as I walk into the pub, I casually toss my Rolls Royce keys onto the bar, and the gals practically throw themselves at me.”
Joes says “Wow, you’ve got a Rolls Royce?”
Mark replies, “No, I’m just as poor as you. I bought this Rolls Royce key fob on Amazon for $20, and the ladies are none the wiser.”
So Joe goes on Amazon and buys the exact same key fob. He then goes to various pubs across the city, with no luck whatsoever.
A few weeks later, he runs into Mark again and he tells him, "Your key fob trick is bogus, I went to at least 20 pubs, no lady looked at me twice, please take this bad luck charm off my hands.”
Mark looks Joe up and down and says, “Maybe it would work better if you took off your bicycle helmet first.”
