Katamari of DOOM!!

I recently started to watch invader Zim again and cam up with a weird idea... What if professor Membrane is actually of the tallest and left for earth.
Here are some supporting facts to point to
#1 abnormally large head. Although all humans seem to have smaller heads, the Membrane family all have large heads
#2 intelligence. Even nasa and mr president are idiots, while everyone in the membrane family are super intelegent
#3 Denial of Dib. Membrane always thinks Dib is insane even though he has proven himself many times. Could Membrane be hiding from his son so that he is not found out?

Here i have some examples of gir's greatness.gir is awesome because he wrote the DOOM song.he is awesome because he LOVES tacos.HE is awesome because he knows how to PARTY.so if one of buddies tells GIR is too stupid and childish for zim,u can slap across the face and tell them wat zim has always said,"YOU LIIEE!"sure GIR isnt smart ou mature,but when that tv screen he makes people laugh so hard that their guts bust and their eyes melt from his cuteness.he is funny and people loved him and still do.so if nicktoons hadnt brought invader zim back,their'd be long faces all over U.S.so all im tryin to say is thanx nicktoons for bringin zim and GIR back to earth.
