Lena and Ole

Lena is pregnant with Ole's child. Late one night, Lena vakes Ole and says, I tink it's time!'
So Ole fired up the Yohn Deere tractor and took her to the hospital to have their first baby.
She had a little boy, and the doctor looked over at Ole and said, 'A son! Ain't dat great!'
Well, Ole got excited by dis, but yust den the doctor spoke up and said, 'Hold on! We ain't finished vet!' The doctor den held up a little girl. He said, 'Hey, Ole! You got you a daughter!' She's a pretty little ting, too.'
Ole got kind of puzzled by this, an then the doctor said, 'Holey Moley, Ole we still ain't done vet!' The doctor then delivered another boy and said, Ole, you yust had yourself another boy!'
Ole was flabbergasted by this news!
A couple days later, Ole brought Lena and their three children home in the self-propelled combine.
He was real serious and he asked Lena, 'How come we got tree on the first try?'
Lena said, 'You remember dat night we ran out of Vaseline and you vent out in the barn and got dat dere 3-in-1 Oil?'
Ole said, 'Yeah, I do. Uffda! It's a dam good ting I didn't get the WD-40 !!!!!!
