Big old Jen had a strap on, Don't carry me off to the hay

The story:

I was in a store singing along with the song that was playing on the store speakers when I realized people were looking at me weird ... when my friend finally told me that I been singing the lyrics wrong for all these years and when when he told me the correct lyrics I started to sing them correctly I thought. Then I looked up the lyrics and found out he was singing them wrong also. Lesson for today don't trust a friend about tongue twister lyrics just look it up!!!!
