That guy from the future

That guy from the future is an unnamed male human who has probably time travelled to the past from the future on more than one occasion. Whoever and whenever he came into contact with the past, he relayed the information that teleporters wouldn't be invented until 15 years from 3011.

Trivia

 * Although he claims teleportation isn't invented until 3026, the Farnsworth novelty disintegrator ray is seen in 3010.
 * He could have been talking about intergalactic teleportation, as the furthest the ray transported someone was from White Planes to New New York.
