Spotted a "one whacker" on Gotham

I'm just getting caught up on the TV series Gotham.

In episode 3 there is a scene a young Bruce Wayne is having "sword fight" with Alfred (his butler and guardian) with canes. Alfred breaks through Bruce's defense and lands a good whack on Bruce's rear... Well, it's a fake whack but it lands.

Then Bruce goes a bit psycho and the "sword fight" ends. Since I was surprised to see that whack land I thought I'd mention it to others.

Someone has posted that scene at, starting at the whack:

It is amazing how many TV shows have spankings or blatant spanking references in them these days.

I think that one is a consequence of sword fighting with a stick. Now if Jim landed a good pop on his girlfriend Barbara's backside, that I'd like to see.
