The pastor of a local church was well known for using acronyms in his sermons. He'd use things like Go N.U.T.S. (Never Underestimate the Spirit) Week. Most often his stories would have something to do with Jesus like the term WWJD. 

One Sunday he was preaching about the creation. Referring to the Earth, the young pastor asked the congregation, "Who made what we're standing on?" After a few moments of silence he said, "Come on folks, you know the answer, who made what we're standing on?" Again silence. Wanting to keep the sermon moving the pastor said, "OK, I'll give you a hint, it starts with a 'G'".

Much to the amusement of the congregation an elderly lady in the back suddenly yelled out, "I know, I know, it's Geezus."
