This society is not overpopulated with eligible members. In the UK, there are the likes of Tim Vine and Milton Jones, both of whom are excellent, a good Canadian (who does the "I asked the librarian the way to the 'Books on Self-Help' Section and she told me to work it out for myself." gag) but whose name,*** momentarily I cannot recall ( a senior moment).
I have yet to find or be impressed with any American, beside Stephen Wright deserving of membership. This makes it a pretty exclusive domain. The problem with one-liners is the amount of material they whizz through in a 10 minute set, let alone longer, and either they've got to churn out new material with rapidity or we hear the same material over and over again and there is only so many times you can laugh at the same gags. And once you've done national television or brought out a CD, your 'cover' has been exposed.
Stephen Wright, delivers his ironic, philosophical, one-liners and gags in his trademark 'lethargic' voice in a deadpan style and the result is a very entertaining performance containing many lines that you will want to tell others. Don't as Wright's skill is in the unique delivery of his lines, and you won't have that ability and your efforts will only bring blank reactions.
A good buy for a bit of a chuckle but has less of a 'play' life than good tracks of music.
*** My 'brain malfunction' has corrected itself (Wiki actually) and the name is Stewart Francis.
