I think it's one of the most common ways of trying to make people laugh. This kind of humour has been around for a long time. It's one of those things that never gets old. However i do strongly believe good comedy doesn't need moments like these.
Watch the movie Ruthless People. It's one of those films which uses the kind of humour where the characters often converse with each other about something, yet neither of them realizes they are talking about two different things and it's really funny.
The most intelligent show i have ever watched is Arrested Development. It was so witty and the dialogue alone made this show. This show used a lot of those double conversational meanings i mentioned above. I much prefer this intellectual comedy as it is so much funnier than a piano lid slamming down on someone.
The problem is writers don't want to challenge themselves anymore so they stick to the same unintelligent gags that everyone else uses, because that's what they masses enjoy.
I certainely believe comedy tastes have changed. However the formula hasn't. Only once in a blue moon does a show like Arrested development come along. These shows are usually too intelligent (or different) for people to get and as a result they don't last.
Just imagining that sounds funny but I know it shouldn't. This is normal because there isn't one particular sound or action you have to do to express each emotion. :D No one says you have to CRY when your sad, why not scream? My grandma smiles when she's sad. Even when her dad died she smiled. XD Keep on laughing, you'll live longer:)
Pain in my rib area everytime I Bend,fart,sleep,sneeze?
It is possible that you may have cracked a rib. You need to go to the doctor, or Urgent Care and have them take an x-ray of your ribs. Another possibility is that you may have pulled a muscle. Being that you work in construction you could have very easily cracked a rib and not know it. Please go to the doctor and have it checked out as it does not seem to be getting better. Good Luck!!!
