Bronson signs up to join the army because the advertisements make it look like summer camp. Later, he changes his mind and shoots himself in the foot, so he won't have to go. This does not frustrate the contract, though the contract may be avoidable on other grounds.

Bronson's self-inflicted injury does not frustrate the contract because frustration requires an unforeseen event outside the control of the parties that makes it impossible to fulfill the contract. His actions, while potentially providing grounds for the contract to be voided on other bases (such as incapacity to perform), do not constitute legal frustration.
