I found a posible TD Servant.

[John Cyrus McCloud]

Website: Youtube
Username: infinitdesu
Apparently, he claims that anyone who thinks the tails doll is a fake is retarded.
I will have to investigate further, but I believe we have a suspect.

New info: His account is closed.

Did he have any videos?

[John Cyrus McCloud]

I couldn't tell, he apparently closed his account and deleted all traces of himself. I only know of him from a string of comments he left on a video that was trying to debunk the tails doll myth.

Eh, probably just some n00b that can't stand that people don't believe in the Tails Doll. Trust me, when I used to believe in the Tails Doll and my parents and friends told me to stop thinking it's real I'd get all mad and lash out at them and try to prove TD exists.

Short thread eh?

Can you show the Comments?

[John Cyrus McCloud]

I will try to find them again.

Hey mythbusterx, I found one of his comments saying that he believes in TD. It's in here: www.youtube.com/comment_servlet?all_comments&v=txLhpTiEf4w&fromurl=/watch%3Fv%3DtxLhpTiEf4w

It'd be Funny if he joined the TDRL and saw us talk about him. Or maybe he's already Here!
He could be you, He could be me, HE COULD EVEN BE--*shot*

[John Cyrus McCloud]

He could be me? No, not a chance. My Youtube Account is 40KEndgame, and as far as I know, that's my only one, although I did try to make a backup under the username John Cyrus McCloud.

He could be you? You are sounding suspicious in that post, but nothing else, so no.

HE COULD EVEN BE--*shot*? Who is *shot*? I don't know anyone by that name, although I might ask TDF if I could make that account as a joke double/universal scapegoat if anything weird happens.

It's a friggen joke...
Some sort of reference to Team Fortress 2.
