It's that day of the month, guys.
Get busy on those balls! Roll 'em around and gently squeeze 'em... Check 'em properly!
Then, if you truly care about the health of any of the males in your life, call, text, IM, email, chat, post on forums, or Skype them all and tell them you care about them and you're letting them know today is:
Buddy Ball Check Day
If you love balls (and you do, don't you? I sure as hell love mine!)...
...don't let any guy you know get it caught too late. Ball cancer is curable if detected early.
