Hm...not sure I could say what the MOST awkward was, but my Dad asks open questions/allows for diologue durings his sermons. One he always asks is what jumped out at you from the scripture of that day. One day, something spoke to me on a completely different wavelength than him. It ended with him stumped, and the church rolling in laughter. My choir mates of the time elbowed me in glee, and to this day I think that all but about three people of that church still think I just wanted to catch him off guard.
