What is the message of this cartoon?

Please I Need Help!!

I'm just guessing, but perhaps the conveying message is how television is changing our ideas to be the same?

Explanation:

because the brains are turning into a square shape

As I previously said in the comments, I would say the message is saying something about not letting content on television change the way you think.    

Explanation:

Another user asked:

"...or that TV is destroying peoples' brains?"  

In reply, I wouldn't say "destroy", because the only thing that's changed about the brains is their shape. The brain is still there and intact-

greet them:

buenas noches.

that is considered night time which is when "good night" is used.

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
