I don't think Sven does any swapping or palming; it's not necessary for what he does in the link.
I know Banachek doesn't.
Thanks, JonWhite, for remembering more precisely than I did about Banachek's stuff.
i can't speak the language (norwegian?) but is the following is correct?
about 3:30 mins in, the host (?) picks a spoon, sven asks him if he wants to change his mind? the host sticks with original choice. then sven places spoons together. around this point (i think maybe :-]) a swap is performed (out of camera shot) before handing the spare spoon back to the host.
the palming mentioned above, i'm fairly certain these occurred in the other of svens youtube clips, with the three georgeous girls while he was tearing the paper.
