Stargate SG-1 Easter Egg - Peter DeLuise Yet Again

In the season 5 episode "Threshold",somewhere in the middle, we see a room with a lotof seemingly randomly-placed candles. A few seconds later, through the glass, we see General Hammond talking to someone. Look carefully at the reflection of the candles in the glass window - the candles in the reflection are arranged tolook like the letters "PD" - for Peter DeLuise.
