Oh biscuits. Marcellus's mouth isn't proportional. Here's why:
You made Marcellus 2 times as tall as Dan but you dragged
Marcellus's mouth to be 2.93 times as wide as Dan's mouth. A
proportional giant would have the same multiple for both.
If Dan's mouth is 4 cm wide, how many centimeters wide should
Marcellus's mouth be?
