Wolfguy Jack was the owner of Greaser's Cafe before it went out of business. He howls, hence the name, although he said that his throat doctor told him not to do that any more. He was the host of the dance competition at Greaser's and gave Homer the Harley-Davidson. He had a female companion who was implied to either be his wife or at the very least his girlfriend, although she ended up leaving him after the closure of Greaser's Cafe.
