A toaster oven was a type of electrical appliance. This appliance was a hybrid with features of both a toaster and an oven.
In 1986, a garbageman had a fight with his significant other over paying sixty dollars for a toaster oven. He refused to pay for the oven. The next morning, he was complaining to his co-worker about the incident when the cloaked HMS Bounty landed nearby. (Star Trek IV: The Voyage Home)
