Each of these three people IMO have a different type of humor that I find interesting:
1) Arvon for his long humor stories which are good reads.
2) johnny for his short one-or-two liners. I think he's a natural and probably a funny guy to hang with.
3) and then there's Donut. I like that name. He/she has a refreshing Aussie humor. I don't quite understand all he/she says but there's humor and usually a respecting intelligence in whatever he/she says.
Thus, my vote goes to all three.
