Another form of comic timing?
Bo Nanas by John Kovaleski
Barkeater Lake by Corey Pandolph
Monty by Jim Meddick
Not only is Barkeater Lake two-for-two (is there another eponymous Barkeater on the horizon?), but it's another double.
There's no question of whether or not the SPP counts today, and Brent made a good argument that yesterday's counted after all.
FoxTrot, on the other hand, doesn't count, since the silence is essential to the gag.
Interesting note on this, I only found out yesterday that Penn Jillette has a podcast. If I hadn't, it's quite possible I wouldn't have understood the punchline of this strip. As they say, in comedy, timing is everything (I'm just not sure if that's supposed to apply to the audience).
