Some of the "other spell to invoke" spells can be this.
Enter "Kiss" while facing a guard or monster. Your Spirit will drop and the game will tell you that you should seek professional help.
Enter "headoff" on anything other than a force field, and the game will say "Excuse me? I beg your pardon?"
Enter "eggs" and the game asks, "Why did you say eggs?"
Try to throw a task item into a recycle bin, and the game will chastize you with one of several amusing lines, such as "It would turn you into a tuna fish sandwich." or "It would turn you into a giant eyebrow."
