This has some great one-liners, short jokes, stories, etc. It is well organized by topic. Amazingly--none deal with nastiness, sex or being hurtful to a minority. Examples: "It was a honeymoon salad--just lettuce alone"; "Never feel bad about growing old--Many are denied that privilege"; Relax, you're as nervous as a turkey in November.
If you deal with the public, you could find some nice opener, ice-breaker one-liners.
