Maybe it is a play on words. "Butt sheets for a bare butts.

I have always hated the Liberty commercials they have ever had with Emu and Dug, except that one. That on made me laugh.
I have to agree with that because is says Don't take if you are allergic and I have to wonder who would take a drug that they knew they were allergic too. I have lost a lot of faith in the intellect of people over the last few years, but would anyone be that stupid and how would then know if they never took it before. If they put as much care into producing the drug as they do in thinking about the wording I know I wouldn't take it under any circumstance.
