A Pun on the Universe.

Pun on ‘mew’- explained. 

Okay, this joke deserves an explanation for so many different reasons.

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. The coefficient of friction (symbolized by the Greek letter mu (μ)) describes the degree of interaction between two surfaces.

Higher and Lower ‘mews’.

A higher mu (mew) indicates that two surfaces in contact have a greater resistance to relative motion. i.e to pull one surface off the other would be hard.

A lower mu (mew) indicates that the two surfaces in contact have less resistance to relative motion. i.e to pull one surface off the other would be easier.

Ergo the cat with the lesser “Mew” will fall off first due to the lesser resistance offered between the cat and the roof.

Meow!
