George's Marvellous Medicine

George Kranky's Grandma is a miserable grouch. George really hates that horrid old witchy woman.
One Saturday morning, George is in charge of giving Grandma her medicine.
So-ho! Ah-ha! Ho-hum! George knows exactly what to do.
A magic medicine* it will be. One that will either cure her completely . . . or blow off the top of her head.
*WARNING: Do not try to make George's Marvellous Medicine yourselves at home. It could be dangerous.
