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

Twelve discantus drumming
Eleven catamites piping
Ten bumblepuppies a-leaping
Nine kvass dancing
Eight weelkes a-milking
Seven saxhorns a-swimming
Six helminths a-cockmongering
Five ga-a-a-amma globulins
Four zygomatic arches
Three epilepsy auras
Two magical sciences
...and an astereopsia in a tyromancy.
