Has Toilet Humor Died?

The other night some of my friends & I were chatting & randomly the topic about Toilet Humor came up. By toilet humor I mean the rude-obscene graphics & comments people would leave behind in school, public, train toilets. There was this time in life when we could not just avoid it. Some jokes/comments which were so dirty yet so funny that you would uncontrollably giggle at them & share them with you girl-friends in hushed voices. Then the trip to the that specific loo would start. The one liners like "apna bhavishya apne hathon mein lo," or others were surely one of the wittiest line one could come up while pee-ing.
I remember once, I was traveling by train from Pune along with some of my friends & my friend went to the sleeper class train toilet & came back with a surprised expression on her face. She whispered hurriedly in my ears saying, someone has made a comment about her in the train toilet. I rushed to go to the left Indian style one. I went in locked the door & hurriedly for that one comment. All I found was "this is for the girl in the red t-shirt, my phone number is this & my D*** size is a perfect fit for you. I stared with a furious expression & abused 'man-stupid-horny-kind.' As I was stomping my way back to my seat, I gave the most hateful looks to all the guys like I was punishing them just through my eyes. Suddenly, a red block. A tall really tall girl wearing a red t-shirt was standing in front of me & she was a bit older than we were & much better to look at. I was so happy to see her for that second that I forgot that how stupid me & my friend were being. I literally ran back to my friend who was so upset & the first thing I told her was "there are other better looking older girls in the train wearing red t-shirts, I just three girls in shades of red..." she gave me this happy look & we continued our journey without worrying about the train toilet.

When I look back, I find the whole thing really amusing & a lot of these images of trian toilets, school & public toilets, train & bus seats & the wooden frames cross my mind with so many of such messages & I Love Yous. I try & recollect the last time I saw one of these & obviously fail to find anything in the recent past. I wonder, if toilet humour has died its own, slow, natural death?
