if that's the only way for someone to get a laugh
Who implied that those of us finding it funny think it's "the only way" to get a laugh?
Those of us with a broad sense of humor find that "using profuse vulgarity" is one of many avenues to "get a laugh." That is of course as long as it is presented in a truly creative manor (such as the video presented here).
Sure it's not for everyone and I can understand that some might not find it humorous, but those who passionately protest this kind of humor, well using Tom's words, "must live very sheltered lives"
Many, many comedians, actors, musicians and public figures have had very successful careers exclusively utilizing this very same sense of humor.
Just to name a few classics:
George Carlin, Andrew Dice Clay, Richard Prior, Bill Hicks, Howard Stern, Lewis Black, etc. Even our friend Bob Saget from the very popular family show, Full House.
Personally, I'm not a big fan of all vulgar comedy, but as you say,
My advise is: Laugh a little to live a little!
