Ok so I'm just curious here...whenever I watch anything I am always seeing people that guest starred in SPN kind of like Where's Waldo...so I was wondering what y'all caught. I've seen a bunch but I'm not going to name all of 'em I'll leave that up to y'all and see if you saw 'em too.

So I spotted the Crocatta (spelling?) -long distance Call in A Haunting in Connecticut

And I spotted a ton in CSI the original but just to name a few...
Max Miller-Nightmare
John Winchester
Harry Spangler and Edd Zedmore (Edd's also a regular in CSI:NY)

Rufus and FBI Deputy Director Steven Groves were both regulars in 21 Jump Street as Captain Fuller and Doug Penhall

and Jenny and the YED/Azazel were both in Lost

Who have y'all seen?
