Steve believes he is having a heart attack after eating too many trans-fats in "Live and Let Fry".
Stan and his gang sabotage one of Roger's Mexican henchmen's lawnmower in "Roy Rogers McFreely", sending him to the hospital.
When Stan sets the house of fire trying to smoke Hayley out of her room in "The Longest Distance Relationship", she lands in the hospital where she sees two doctors making fun of a janitor and shames them into leaving him alone. The janitor turns out to be Millionaire Matt Davis, who takes on odd challenges to experience life. She returns to the hospital 60 years later, unable to cope with Jeff's return when he uses a wormhole to find his way back to earth, but fails to calculate for the time.
