Before performing a baptism, the pastor approached the young
father and said solemnly, "Baptism is a serious step. Are
you prepared for it?"
"I think so," the man replied. "My wife has made appetizers
and we have a caterer coming to provide plenty of cookies and
cakes for all of our guests."
"I don`t mean that," the pastor responded. "I mean, are you
prepared spiritually?"
"Oh, sure," came the reply. "I`ve got a keg of beer and a
case of whiskey." (A Funny Stuff, http://www.afunnystuff.com/jokes/Religious-jokes/Baptism-preparations.html)
