What is FBI Agent Fox Mulder's badge number?

The badge number is.............. JTT047101111

He says it in the following episode > F. Emasculata ( Season 2 Episode 22 ) @ 17:19 mark

In 7x08, The Amazing Maleeni, a close up shot of Mulder's badge is shown @ 42:25 - it shows clearly "Agent Number 22791"

On a slightly related note, in the show Bones, Agent Booth's number is 22705. This might be some sort of 'made for tv FBI numbering' similar to how tv characters' phone numbers almost always start with "555" which is a non-existent prefix in the US.

Also interesting: Mulder is said to have re-opened The X-Files in 1991 (w/ Fowley) and Bones first aired in 2005 (the beginning of the FBI-Jeffersonian partnership). 91 and 05 being the only difference in these 2 FBI Agent's numbers.

Then again this may all be a coincidence brought on by watching too much X-Files.
