Oooo! That is much better than "Cathy is a b**** and Annie is sweet!" which
is how I learned it. Leads to a life-long bias against Cathie's and for
Annie's! Just like Charlie brown telling his friend that the best way to
discipline a puppy was with a rolled up newspaper, and then Snoopy comments;
"Yes, but it does lead to a rather distorted view of the press"

Easy way to remember this, look at the diode symbol and you will see that
part of it forms a K, which stands for Kathode.  Just remember not to spell
it like that when you write it :)

i.e.

(K)athode  Anode
