In a strange fluke of nature, ibuprofen pills lose most of their painkilling effectiveness when they aren't actually taken. Even more shocking, leaving the pills somewhere doesn't count as “taking them.”

I hear some people are trying the “remember to swallow the pills” strategy, but I don’t know if it’ll catch on.
