His yard was much larger, so he went to Johnny and said “Johnny, weboth need a lawn mower.Why don’t we go shopping and get the lawn mower together.”Johnny and Mark found a suitable lawn mower for $10,000. Johnny actually talkedto the salesmen. And the salesmen agreed to extend Johnny a loan to purchasethe lawn mower if Mark would orally contract to stand as a surety for Johnny ifthe payments were not made on time.For two months, Mark uses the lawn mower more than anyone. Butthen Johnny fails to make payments and the salesman sues Mark under the oralcontract. What will be the likely disposition of the case?
