Gary, a farmer in Nebraska, is having financial problems. He begs his friend Fred for money, and agrees to let Fred assume control of his farm's finances. One week later, $30,000 is wire-transferred to Gary from the Rexford State Bank. Gary thinks that Fred would be responsible for repaying this sum. The following week, a man who works for Fred stops Gary on the street and asks him to sign a receipt for the $30,000. Gary signs without intending to commit himself to repaying the money. In fact, the document Gary signs is a blank promissory note, payable to Rexford State Bank. Someone later fills in the blank, writing in $50,000 instead of $30,000. Fred had received a sum of $50,000 before transferring $30,000 of it to Gary. When Rexford State Bank sues Gary to enforce the note, Gary claims he does not have to pay anything to Rexford.

Would anyone be holders course due?
