The Surgeon's Lab Coat

The Surgeon's lab coat is a piece of clothing in Fallout 3.

Characteristics
Worn by The Surgeon, this unique version of the Vault lab uniform grants an additional bonus of +10 to Medicine. It can be repaired with Doctor Li's outfit, Enclave scientist outfits, lab technician outfits, scientist outfits and Vault lab uniforms.

Location
The wearer of this coat is found on the 2nd floor at Red Racer Factory. You can kill the Surgeon and loot the corpse. Alternatively, you can obtain the coat without killing him or her by reverse-pickpocket better armor into his or her inventory, then pickpocketing the coat when he or she equips the better armor. Wearing the ghoul mask helps since the Surgeon is part of the feral ghoul faction.
