Years ago they used to put people in stocks and pillars so that everyone could throw rotten veg at them, you Americans sent us David Blaine and we thank you....
We Brits are now going back to medievil times thanks to Blaine and he is the target of the veg, or maybe eggs, or for the sporty chaps "golf balls".
Seems strange he used Tower Bridge, all the evening drunks use that bridge to go home after a binge.
