Legendary tough-guy actor Elisha Cook Jr. appears as Uncle Albert, Willie's least favorite relative. Paying a visit to the Tanners, the irascible Albert insists that he's undergone a character transformation and is now a sweetheart. But no one will ever know if this is true: After taking one look at ALF, Albert drops dead of a heart attack! All of this has a remarkable effect on ALF, who, though he's perpetrated a lot of mischief in the past, has up until now never actually killed anyone.
