Sneaky,
Thanks. The spar pro is definitely getting a work out.
Dad's doing much better today. They took 30cc of liquid out of his knee and gave him some pain killers and industrial strength anti inflammatory meds. I think this is the eighth time we've been to hospital this year (thankfully most visits were NOT to the ER!) and he's really doing pretty well overall. (He aced his balance test a couple of weeks ago - I told him they grade on a curve. He said something about me being a smart ass.
Mois? 
)
Thanks again for the laugh and thanks to Martin and others for their kind words.
