Ozzy and his wife are one of the UK's richest couples, according to the "Sunday Times" Rich List. They ranked at number 458 in 2005, with an estimated £100 million earned from recording, touring, and TV shows. Osbourne has over 15 tattoos, the most famous of which are the letters O-Z-Z-Y across the knuckles of his left hand. This was his first tattoo, created by himself as a teenager with a sewing needle and pencil lead. A longtime fan of the comedy troupe Monty Python, in a 2010 interview with "Us Weekly" Osbourne stated, “My favourite movie is "Monty Python's Life of Brian"”. Osbourne suffered minor burns after a small house fire in January 2013. On his 65th birthday on 3 December 2013, he asked fans to celebrate his birthday by donating to the Royal Marsden cancer charity in London.
