What follows can be told as individual jokes, or combined for a double-whammy.
1:
I got on a train today and found myself paired up in one of the sleeper carriages, opposite a very beautiful woman, who was reading a book entitled 'Sexual statistics'.
She didn't stir as I sat down, so I briefly looked around the carriage and then pulled out a magazine.
After a few minutes, I noticed her look up from the book and our eyes met. Getting over the initial fear of speaking to her, I inquired "Good book is it?"
She put the book on her lap, took off her reading glasses and put them on top, then leaned forwards and said "Actually, it's particularly interesting, did you know that the native American Indians have the thickest male reproductive organs, and the Polish have the longest?"........"Oh, please forgive me, my name is Jane, what's yours?"
I replied "Tonto Kowalski."

I was on a train, in a sleeper carriage, and got chatting to an attractive lady who was in my compartment.
It got late and we both got into our bunks, she took the bottom and I took the top.
It started to get quite cold, so since she was closer to the blanket storage compartment, I said "It's pretty cold in here, would you mind passing me another blanket?"
She said "I've got a better idea, let's pretend we are married."
Enthusiastically, I said "That's cool with me!".
Then she said "Get your own frickin blanket"
