My favorite is #18.  There's just something about that slight reactionary pause after the first toss that totally sells it for me. 

I had some sadistic glee viewing #13, though I have a feeling I've seen a play on this particular gag before.  #6 tries a bit too hard -- comparatively, #15 more elegantly portrays the point with its simplistic approach.

I giggled at #19 and #26. And #6, the last line.

for some people they are.. i'm sure each of us knows at least one person who puts in a 40 hour gaming week...
