Worthless postOften times overheard conversations tend to be the most humorless. That is to say, most people are talking gossip or completely inappropriate discussions for public settings. You never really hear anyone having a public discourse of how paint sticks to walls or whether or not gravity allows you to pour water down one nostril and have it come out the other. I mean, those are usually semi-humorus or more likely "entertaining". They'll at least be something to chortle at when walking with friends. Its the passing banter that is completely obscured by some other noise, that cuts off the meanings of sentences and whatnot to suprise you with oddities that are really the most humorus.
So, all that build up comes to this: I heard someone say as I was sitting at work, "The latest issues are 'Jaw Surgery' and 'Ed'"
