I was on the Ave Lubeck (ex pau cassals, ex dawn merchant) when she was chartered by T-Link to run from Palermo to Genoa and became the T-REX, there was actually talk of painting a great big dinosaur on the funnel until the charterers realised how much it would cost!
Who the f*** calls a ship T-Rex?
EDIT: she was actually the T Rex rather than T-Rex, those nice chaps at the MCA pointed out that you are not allowed to use symbols such as - in a ship's name under the UK flag.
