This is just funny
On the twelfth day of Christmas, chippychimp sent to me...
Twelve decepticons drumming
Eleven combiners piping
Ten autobots a-leaping
Nine headmasters dancing
Eight transformers a-milking
Seven b-movies a-predaking
Six lights a-gaming
Five ato-o-o-omic fireballs
Four go bots
Three barenaked ladies
Two boondock saints
...and a devastator in a shifty.
