Get a little sketch book or tablet. Every time an ad comes on, draw an object (or dog! Or person!) in the room with you. Try to do the whole sketch over a single ad break, focusing on the biggest, most important shapes first. You'll learn to draw very quickly.
If you already know how to draw, draw. Use it or lose it!
Disclaimer: am artist, possibly biased. Doing art for its own sake is fun for me, so it doesn't need to have a 'point.'
I seem to recall Maverick(1994) having a good card game as a central plot element, which takes place on a river boat casino. It's also just a really fun movie about three competing con artists (played by James Garner, Mel Gibson, and Jodie Foster).
It's been a few years since I've seen it, and it's set in the old west, so sorry if it has any racisms I forgot about!
