ROFL.
That explains it all.
In my younger years I once received a massive dose of tetanus vaccine. I fell out of a kayak and cut my knee open, right down to the cartillage. The nurse at Builth Wells Cottage Hospital was a bit over liberal with the vaccine, bless her. This was before I was a TD fan. Can't be just coincidence.
She also said she'd put in 9 stitches. My GP said "Are you sure?" as he took out the twelfth one. A week later he had to take out a thirteenth when the scab came away. I strongly suspect she'd been at the surgical spirit.
