What're everyone's opinions towards one-liners and puns?
I don't mean things like:
"I had a boiled egg, it was egg-sellent", but more thought out punchlines and a play on a phrase. The same style as the likes of Milton Jones:
"My grand-dad covered his back with butter, after that he went downhill very quickly."
Stewart Francis
"I was sitting in traffic earlier, inevitably I got run over."
Steven Wright
"I spilt spot remover on my dog, now he's gone."
Of course the very memorable from Airplane!:
"Surely you can't be serious?"
"I am serious, and don't call me Shirley."
There are several comedians, (just thought of Tim Vine), TV shows (Not Going Out) and movies (Airplane!) that are very successful that use puns of the sort pretty much all the time, yet some people think it's "the lowest form of wit".
Thoughts?
