7 short jokes for a good Tuesday

I asked my friend when his birthday was, and he said, "March 1st".
So I walked around the room like a soldier and asked him again.

I left my job today. I couldn’t work for that man after what he said to me.
He said: "you’re fired."

My wife and I were walking through the park today and we passed a large groups of nuns.
I said wow what an opportunity for a joke, but I’ve got none.

Daughter: "How do I look, Dad?"
Me: "With your eyes, sweetie."

A dad went into his 13 yr old daughter's bedroom to find her smoking.
"How long have you been smoking?" he shouted.
"Since I lost my virginity," she replied.
"You lost your VIRGINITY?" he shrieked. "When the hell did this happen?"
The daughter replied, "No idea, I was drunk!"

A sweet old lady on a bus offers the driver some peanuts. He eats a few and asks her why she isn't having any herself.
"Oh they're too hard on my poor teeth, I couldn't."
"Why did you buy them all then?" wonders the driver.
"You see, I just love the chocolate they're covered in!"

"Come into the bedroom and I'll show you a good time," I said to the wife.
When she came up I showed her pictures of me and my mates before I met her!

Evolution theory

In 1858, the Wallace-Darwin theory of evolution was first published at the Linnaean Society in London*. The previous month Charles Darwin received a letter from Alfred Wallace, who was collecting specimens in the East Indies. Wallace had independently developed a theory of natural selection - which was almost identical to Darwin's. The letter asked Darwin to evaluate the theory, and if worthy of publication, to forward the manuscript to Charles Lyell. Darwin did so, almost giving up his clear priority for he had not yet published his masterwork The Origin of Species. Neither Darwin nor Wallace were present for the oral presentation at the Linnaean Society, where geologist Charles Lyell and botanist Joseph Hooker presented both Wallace's paper and excerpts from Darwin's unpublished 1844 essay.
