To quote the wise philosopher Todd Chavez,
“Fool me once, fool me twice, fool me chicken soup with rice.”
fool me once, shame on -- shame on you. fool me -- you can't get fooled again.
gotta be one of the sayings of all time
Also in that same episode of television is the wise quote “Fool me once, shame on you. But teach a man to fool me, and I’ll be fooled for the rest of my life”
please go watch BoJack Horseman (if you are at least 16-18 years of age and are ok with watching a very bleak and upsetting show that happens to also have some of the best character and comedy writing on TV)
