a snail reading mail on top of a nail

it tells a tale of a quail flying in hail
while flying on a gale it follows a trail into a vale
through the thick veil it spots a bale of hey in jail
trying to assail the tail of a whale
landing on a scale it disturbs a pale male weighing kale
which is stale and frail and thus on sale
letting out a wail it starts to flail and knocks over a grail full of ale
attempting to bail it flies into a sail ending in a fail

making the snail exhale at that last detail and setting out to Yale
following a rail it will prevail to regale old Gayle who can only read Braille

in cooperation with a rhyming snail
