Lucy and Zehmer met while having drinks in a restaurant. During the course of their conversation, Lucy apparently offered to buy Zehmer’s 471.6-acre farm for $50,000 cash. Although Zehmer claims that he thought the offer was made in jest, he wrote the following on the back of a pad: ‘‘We hereby agree to sell to W. O. Lucy the Ferguson Farm complete for $50,000, title satisfactory to buyer.’’ Zehmer then signed the writing and induced his wife Ida to do the same. She claims, however, that she signed only after Zehmer assured her that it was only a joke. Finally, Zehmer claims that he was ‘‘high as a Georgia pine’’ at the time but admits that he was not too drunk to make a valid contract. Explain whether the contract is enforceable.
