During the midst of rush hour traffic, a bus driver pulled over to the next stop just in time to pick up a boy carrying a strange looking box.
Curious, the bus driver looked into the box and saw four tiny little kittens - so young that their eyes hadn't yet opened.
"I haven't seen kittens that young for a long time," the bus driver said, "What are you going to do with them?"
The boy, looking a bit puzzled, replied, "They're not kittens, they're athiests and I am taking them to church". The bus driver decided to leave that one alone and continued on his rounds.
A few days later the boy got on the same bus with the same bus driver. The bus driver recognized the boy carrying the curious box and said, "I see that you brought your athiests with you again, are you going back to church?"
The boy replied with a grin, "They're not athiests any longer, they're Christians - their eyes have been opened!"
