Flashman vs. Zork (1x30)
:
The aliens' next visiting tenant is none other than the famous superhero Flashman (whose name is a cross between that of The Flash and all superheroes whose names end with "man"). Then his brother and rival Zork moves into their house and battles against him. The aliens' only chance of removing them from their house is to call their mother, who is referred to as "Mrs. Hero" over the phone.
