sorry, the only out of the ordinary thing i see besides the general stupidity of this cartoon is the oversize book the phone is on.

Take a closer look at that phone. Go on. Take a big, steaming GAWK at that phone.

ooooohhhhhhhhh!

The phone exists between worlds. Not only can you open the book while the phone is still on top of it, you can also pick up the receiver without picking up the receiver. And its a rotary.

Wait what. Other than it being totally shittily drawn and having completely whacky perspective\continuity errors I don't see anything special... what am I missing damn it.

Look at both of the receivers.

Both of them.
