Finding money

If you see change on the street, do you pick it up? Does it depend on the denomination?

I wasn't raised by Depression era babes for nothing. I am genetically programmed to pick up anything I find -- pennies included. Not only that, but I can't help reciting this little verse at the same time:

Find a penny
pick it up
and all today
you'll have good luck.

I found a penny on the sidewalk on my way to work this morning and as I bent to retrieve it, I amended my little ditty to this:

Find a penny
pick it up
and all today
you'll have H1N1.

Please come and visit me in the iron lung.
