Monty

Monty is a level 12 quest giver and "Rat Extermination Specialist" located on the Ironforge side of the Deeprun Tram. It is common for Horde players who have entered the deeprun tram to kill him, triggering a "The Deeprun Tram is under attack" message in defense channels.

He starts the following quests:

See List of Deeprun Tram NPCs.

Trivia
For Horde players wishing to infiltrate the tram, Monty does not aggro unless provoked.

He also has a very, very, VERY short respawn time. Just a couple of seconds. This will make Horde players able to create a big pile of Montys.
