"From these tankards ordered one to seven
Choose one and fill from the water given
Passage is granted to the wise and brave
But danger lurks for the fool or knave

Two will steal your sense, three will steal your skills
Just one will see you safely through - but one will see you killed.

When finding a sense-stealer, always check its right
There on its shoulder will quietly sit skill's blight

On both of death's shoulders you'll find identical twins
But death sits not at a terminus and nor does the choice that wins.

This should leave you pondering a quandry of two
Know that success sits before doom, and this should do"
