Borderlands 2: Get Dwarves Drunk
Equip the mission specific gun, Miss Moxxi's Grog Nozzle. Aim and fire on any of the Dwarf Miners in the area. When you hit them with this gun they will become a Drunk Dwarf which will be chasing you. The Grog Nozzle has a very high chance of slagging the dwarf so expect it.
