Shantanoo (on the phone): How do you use CVS from within emacs?
Manas: Don't know, never done it. Phattu here uses Emacs, ask him. (Manas hands the phone to an unenthusiastic Ashwin, aka Phattu.)
Shantanoo: Hi, I'm Manas' friend. How do I commit to CVS from emacs?
Phattu: (After thinking for a couple of seconds) Alt-X shell ... cvs commit.
Laughter all around.
For those who didn't get the above joke ... well, might as well give up, you won't understand it even if I explain.
