It's not pining, it's passed on! This bird is no more! It has ceased to be! It's expired and gone to meet its maker! This is a late bird! It's a stiff! Bereft of life, it rests in peace! If you hadn't nailed it to the perch, it would be pushing up the daisies! It's run down the curtain and joined the choir invisible! This is an x-bird!
It's funny because I was just explaining to my kids how we owe the internet definition of "spam" to Monty Python.
