In order to commemorate The Procedure in all its glory, the first person to guess the 3rd member of the team will win a copy of Dr. Pauly's Lost Vegas book. TheMark, Otis, and GRob are not eligible for this prize.
Have at it.
UPDATE: Nobody is correct thus far. Also, JimTheKnife guessed AlCantHang and he too is incorrect.
UPDATE 2: If for some reason you already have Pauly's book, I'll substitute Jim McManus' Cowboys Full book as the prize.
HINT: Said person has been mentioned in this blog several times.
