I sneeze, a lot.
People that know me know not to bother saying "God Bless You" after the first sneeze or the second sneeze. Usually I sneeze in 4 shot bursts.
Yesterday, as I was walking into the station, I was on sneeze number two, and someone said God Bless You. I replied with a sneezed "AAAAAATHANK YOU" because I can actually talk when sneezing sometimes.
He walked down the street laughing his ass off.
