Well, John;
Here is a possible scenario.
After your liquid lunch with Jim Beam...
During your "Happy" hour nap...
A herd of olliphants wandered through your
yard and casually walked on your foot...
After all, YOU walk on it why can't they...
Being nice olliphants they were gentle and carefully did not wake you...
I'm sure they have been huddled around their cell phone reading Permies and chuckling over your confusion!
