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...
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
