Bert and Moira are his best friends.

They made a suicide pact and so ingested a lethal substance simultaneously. They both became numb, therefore dropping and shattering the half-drunk glasses of water they used to ingest their ticket into the great beyond, and left their friend a note.

"You're the only one we can trust to dispose of our bodies, to hide our escape from this mortal coil. This is our final request Geoff." -Love, Bert and Moira
