Fame, boys and girls, fame and glory in the form of a London cab (only it was in Oxford):
Unfortunately the above-mentioned fame and glory is on the cab's ass, but we all have to start somewhere.
Maybe some day I will make the passenger door.
So, Po stands for Polonium, only one of the nastiest most radiotactive elements around, used for poisoning Russians and being generally volatile and terrifying.
It is also the name of a cuddly, lazy kung fu panda, who does know how to kick butt, or at least how to sit on top of butt.
Kind of a contradictory combination, but add to that mix a dazed and confused seamonkey who does not know her head from her shrimpy tail, and it kind of makes sense.
You try being a cuddly and loveable deadly toxic radioactive element. Melting people's hearts takes on a whole new meaning.
