Buried my dog behind the barn
Times got tough had to sell the farm
( Sorry to interrupt but these two things aren't related, you understand.
I mean the dog dying wasn't the reason we had to sell the farm. It's not like the dog did the accounting for the farm. Or because the dog died we stopped working altogether).

Had to leave the crops in the ground
Moved our selves into town.
(Actually we simultaneously moved into town and left the crops in the ground so either of these sentences are interchangeable, one can go first our second, you understand).

Continuing.

Our family took it very hard
In town we didn't even have a yard.
(We didn't have a yard but there was a dog house but irony being what it is, we left our dog back in the farm buried behind the barn, you understand, and our family did take it hard. Grandpa was led off in a straight jacket. When I asked where they were taking him, the man said were taking him to the funny FARM. Yeah, the funny FARM.  We weren't laughing We don't like irony. Never have never will).

Back to the poem.

Without money that we still lacked
We devised a plan to get the farm back
(I'm sorry I have to interrupt this poem once again with my parenthesis  because I just can't go on with all the sordid details of us breaking grandpa out of the nut house, digging our dead dog up from behind the barn, grandma seeing a *******, us poisoning those aforementioned crops and feeding them to the bankers dog, the one who foreclosed on us. Not the bankers dog, the dog didn't foreclose on us it was the banker, you understand.)
Consider this the end of the poem then. Go back to what you were previously doing.
