You know you're playing in front of a really rough baseball crowd when they throw safes onto the diamond. Thankfully, the umpire got the call right, and maybe the ballplayer got what he richly deserved. All those sporting fans and joke lovers you know who are turning another year older whether they want to hear it or not, will be laughing with good cheer and gusto when you slide them out this hilarious Happy Birthday greeting. The ballgame humor will hit them square in the funny bone, as they gratefully and gregariously field the comically illustrated, gag captioned Birthday card.
