Professor Icenstein:
Aha! Just as I thought. The key element in Beef's personality is rage. He would rather be angry than anything.

Doyle Cleverlobe:
Well that's the truth, but what's it got to do with Martian Mumps?

Professor Icenstein:
Aha, when you made him angry, it brought back his true self, thus curing his Martian Mumps

Aimee Brightower:
You mean we have to make people angry to cure 'em?

Professor Icenstein:
No, no, no, no, no, that only worked with Beef because it's his strongest emotion. Someone else might be cured by laughing, or hugging, or zinging a zong.

Beef Bonk:
That's disgusting!
