Parent: Oh, where's that lovely detailed globe of the world gone, Mrs Klaptrap?

Teacher: Too complicated for suburb kids, so we got an elmo in. It only shows where North America and Iraq are, and later we'll add the ballistic missile trajectory to it once they're up to third grade.

A red furry puppet thing that has a pet goldfish.
This "puppet" is known to have a gun in his diaper stash.

WARNING! DO NOT MAKE ELMO A MAD PUPPET!!!
He will kill you in your sleep or show up in a mirror whenever you look in one.

DONT LOOK IN A MIRROR THAT HAS A MIRROR ACROSS FROM IT or then Elmo comes to be more powerful because he is now a polturguist!

EXAMPLE:
Cally: "Wanna summon Elmo in the mirror?"
Haley: "How do you do that?"
Cally: "Yell, 'ELMO YOU ARE A GAY PUPPET' into the mirror and wait."
Haley: "Ok... ELMO YOU ARE A GAY PUPPET!"
*Elmo appears in the mirror and shoots them*

Get the elmo mug.
A high pitched freak of nature that has no moral, educational, or really any value whatsoever. In fact, it's been studied that television causes some autism, so elmo is really just making your children retarded.
