Half-Life: Opposing Force Easter Egg - Scientists Humor in the Duck Jump Course!

There is an egg in this topic about going to the duck jump course from the original "HL".When you get there,get the shotgun and kill the aliens so they don`t annoy you.Put noclip on and fly up the the scientists observation course (Word Of Warning:Do NOT go up to the teleport thingy),look at the clipboards bottom right corner and look,Gordon with easter eggs in his eyes!I guess you can really call this an easter "egg"!You can also see this photo in blue shift in the "Out Of Order" toilet inside door.Maybe the scientists took a photo of him as best hazard courser of the month!Or maybe just those d00ds at Sierra or maybe Valve...Once again they have me laughing!
