Sick joke

The kid is ill again. I must have spent half my bloody wages on Calpol and Medised since his birth. I took him to the doctor yesterday and got told that he (the kid) is ill and needs to be dosed up with Calpol and Medised. I reckon I could do this doctor lark, sounds very easy. No matter, as I was leaving, the doctor said 'See you soon' to which I replied 'I hope not'. He shot me a glare.

Either:
a) I'm not as funny as I think
b} The doctor doesn't have a sense of humour
c} The doctor has heard this joke more times than the kid has had doses of Calpol and Medised
d} All of the above

By the way, I typed this whole post with my left hand, surely a first in bloggage history.
