All things to all men, does that sound like someone who doesn't know how to hold an audience to you? Chris Rock has nothing on old St. Paul.
How can you reconcile this now-proven reality with the data contained in Acts 20:9 where Eutychus 'fell asleep' while Paul was preaching? Did he have no sense of humour? Was he just a really young 'young man' and needed a nap? Was he narcoleptic?
I would like to suggest that perhaps a psychosynopticising reading of the text may provide the answer. And so, I present to you my alternative reading of Acts 20:9:
lachschlaganfall
n. a condition in which a person falls unconscious due to violent laughter
