At the beginning of the episode, we see Ted's screen name is TeddyBear616.
This is a possible reference to the fact that the Marvel Comics original universe is usually referred to as "Marvel-616." 616 is the the universe in which mutants first originated.
It could also be a reference to the "Number of the Beast" from the Book of Revelations. A recent discovery proved that the number is really 616 and not 666, as has been believed for centuries.
