During the Gallifrey One convention held in Los Angeles in February of 2010, I was following the Gally discussion via the TARDIS Databanks Twitter account and noticed a lot of mentions of this Doctor Who sketch put on during the masquerade.
I also heard a lot of people praising this guy throughout the weekend on his spectacular Brigadier Alistair Lethbridge-Stewart costume which you see featured during the skit.
Check out the full (and very funny) skit “The Unsung Hero” from the Gallifrey One Doctor Who convention in February 2010:
