So hubby and I are watching Big Bang Theory repeats for the umpteenth time, this episode is when Howard has a rigged card trick he's using to frustrate Sheldon. At the end, Sheldon insists he select the card, not Raj. Raj sees the card and motions with two fingers over his heart. The audience sees Sheldon is, indeed, holding the two of hearts.
The goof? As Howard is talking the cards from the box, the two of hearts is very clearly on the bottom of the deck. Sheldon chose a card from near the top.
I suppose the entire deck was twos of hearts, so they could film the scen without pausing to change Sheldon's card. But it was visible.
Anybody spot a similar goof on any show?
