Comment hidden because you are ignoring dag.(show it anyway)

Penn might need to adjust his Low-T treatment.

I have to admit I hated the guy too, but that was a great trick.

I think I see how this is done. Watch at .25 speed around 3:58. As he's going through the deck, you can see he's filtering face-up cards versus face down cards. Then just before the reveal, he does a "cut" which aligns the cards. He has Penn and Tellers cars set opposite...if they went in face-up then he put them in the face-down cut, if they put it in face-down, he put it in the face-up selection. I'm surprised that they didn't realize how this was done. Pretty basic, actually. This is the phantom shuffle method.

Haha @ Penn picking the three of clubs.

I think you have to be right. That's the only opportunity, and you can see it's slightly fishy as they're being slotted into his right hand. He also makes sure to go through the whole deck instead of stopping once the chosen cards are inserted. Good catch.

EDIT: Of course it helps to see the trick multiple times...

You're making an assumption about the show and about Penn's reaction ;0)

I think you're totally right. There have been a few tricks that were good, but still leave some ideas as to how they could be done, but the trick that still has me in disbelief and leaves me with zero clue as to how it was possible is this one: http://videosift.com/video/Shawn-Farquhar-s-Fantastic-Card-Trick-Fool-Us-Penn-Teller

Shawn Farquhar gets just Penn's signed card flipped reverse with all cards in new-deck order INSIDE a box and wrapped in plastic! WTF!

Digging through the YouTube comments followed by a little further searching, yeah, apparently the basic idea is he's sorting the cards face-up/face down underneath as he fans them out near the end. A description which probably doesn't do justice to the amount of dexterity & concentration required while also keeping up the patter.

Inevitably you can also buy the technique video from the guy's website: http://kostyakimlat.com/roadrunner-cull.html

Wow, was it over four years ago for UK's series?
