Watch out for those cuddling pagans!

On the twelfth day of Christmas,
happypete sent to me...

Twelve mathematics nesting
Eleven spaceships handfasting
Ten pagans a-cuddling
Nine conventions running
Eight relationships a-reading
Seven books a-programming
Six computers a-parenting
Five fo-o-o-our quarters
Four douglas adams
Three computer games
Two weight watchers
...and a cisco in a libertarian party.
