Yeah but then I become radioactive.
I was at the supermarket earlier this morning, and accidentally swallowed wrong. As a result, I coughed.
There was only one person in the same aisle as me. You would think I gave her the kiss of death.
If you have a really dumb boss, you might want to be radioactive for a week or two...then when the tests are readily available you can take a test, test negative, and everybody is friends again....
