I remember the first time that I heard a sermon at my current church. When the pastor walked up to the pulpit, and his mannerisms during the sermon, it all struck me as something that I had seen before. It finally hit me, he had the same walk and gestures as Robin Williams. I actually shared that with his wife.
It might be my photographic memory. I just hated not finding the exact poses of the celebrities that went with the avatars.
