This shirt was accidentally put in the wash with a red shirt...
...which unfortunately ran.
It was very lucky it wasn't a white shirt,
because it would have turned pink.
(pink shirt used as an example only, no white shirts were harmed in the making of this post)
To hide the green shirts blemishes cosmetic surgery was performed...
...and the green shirt was saved and made beautiful. And all the shirts lived happily ever after (until the next time one of them got dirty).
Note: I have a number of shirts in the same style in different colours. Currently most of them need ironing.
