Potheads

I just got my highest scoring single word in Scrabble. My opponent started with "Size" starting on the center tile. I was very surprised to see the letters "photaed" in my rack, that's right, all seven tiles could be used. Now how do I fit that in? You're right, I played "potheads" from the top middle triple word score tile to the. 54 points for the word and 50 for using all my tiles. Total 104.
