My friend John, who saw through His preacher dad's Presbyterianism By the time he was fifteen, Still searches for unicorns, Keeps his metal detector ready By his underwear drawer And last night dreamed He was Marco Polo. Imagine his surprise this morning, This very morning, Pulling out his favourite boxer's, black silk, Extra large with the yellow Batman logo, And there behind them-- No idea how long it had been there-- A smiling rhinoceros.
