It's not a new story. A bloke in Sydney throws a sickie and is caught out online. But you have to admire his bravado, especially when his trousers are down.
He had insisted on his rights in relation to providing evidence for a sick day. Unfortunately, his Facebook page told the true story including, inter alia, "i'm still trashed. SICKIE WOO!"
The part of the story that gave me the biggest laugh was his reaction when caught: "HAHAHA LMAO [laughing my ass off] epic fail. No worries man."
Apparently a call centre worker, so I guess he figured such jobs are a dime a dozen, which they are. The full story - here - is quite funny.
