Food For Thought

Every so often I find something on the internet that is cause for pause.  It could be something ridiculous, or amazing, or baffling, right or wrong, flippant or chipper.  Something about the link makes me stop for a moment and either retch or rejoice.  I usually only share these with my pen pal, Kim, but today I've decided to cull through some of the "FFT's" (food for thought) and post them here.    The headings are what I think of when I see the image.
