Unless I'm mistaken, Airman Aussie Astro was going to testify that he had no clue why it was funny.
It would be easy to say I don't know why it is funny, it just is. But, my evidence is that this is not funny and never was. All the focus on the wiener means important issues are being missed. I am surprised and a little disappointed that no one has actually figured it out... Who was the batter? When Oliver Stone gets around to making a movie about it, the guy will be an undercover Astros coach and the sign was for the next pitch, fastball to pooholes junk.
