Felger may be the most annoying character
That bumbling scientist who miraculously manages to rescue SG-1 with his colleague in one episode, and then later on, paralyses the entire Stargate network with his dumb virus, although that's not entirely his fault.
I did however like the endings when his imagination leads to a medal ceremony, and then Carter calling his female colleague (whom he's hugging and kissing) a trollop! :D
