man perl
man perldoc
perldoc -f <functioname>

That's what I'd put on a Perl mug: some of the important things (IMHO) to know as a perl programmer. I'd spiral the text around the surface of the mug, in nice pretty fonts and colours. That's just what I'd do, though. I don't really like regexp syntax, or coffee for that matter, so maybe I'm the wrong one to ask.
