Do you think it's ironic/comedic/pitiful....

Certainly not limited to, nor scientific, but I call it "Old People" syndrome. Yes, many are very sharp and full of experience and wisdom. But for the few others, they are stuck in some time warp, nothing else to focus on, too much time on their hands, nor anyone that really listens to their nonsense.

Yes, I call it pitiful .. 

I find it pitiful and see and hear it quite often. I don't think anyone could quite exhibit my behavior and I sure don't try to complain about people as everyone is different and each has their faults and each has their good points. It's a shame that happens but it's a fact of life.

I think its interesting.

isn't it ironic
don't you think?
sad too...

It can be any or all of those things, depending upon the person and the specific behavior, as well as how they react to that behavior in others (i.e. holier-than-thou, non-stop ranting, cluelessly - that one can sometimes be quite funny).  

I think it is the height of hypocrisy and it annoys the crap out of me.

Lots of people do it.  My husband's grandmother does that all the time but when she does to my hubby he always tells her "I learned from the best!"

Yep.  One needn't go further than here to see/hear it.

sounds hypocritical to me

Oh yes,that's sheer hypocrisy

In the case of those commercials who show people deformed by oral cancer from smoking who are telling us not to smoke---I find it more tragic than anything.
