Psychotic Hot Tub is performed when the hot tub reveals its evil nature to Stan after it swallows Francine and Stan refuses to let her be killed in "Hot Water".
Hot Tub: You know what? You can be with your wife again. Because you'll both be dead!
Stan: Ahh! Ahh!
Hot Tub: Once again, it is the hot tub
With a taste for blood and I don't need you Stan
Don't want to be my wingman, fine
I'll just carry out my evil plan
I've got the house, got the phone, gonna call
Some freaks that I don't know too well.
Don't want to partake with me? You and your wife can both go to hell
