Mmm, tastes like chicken

Everything weird and unusual that people eat seems to always taste like chicken. A guy who's eating something gross and slimy from inside of a tree would say "Mmm, tastes like chicken". A guy who's eating a weird fuzzy bug from underneath a rock would say "Mmm, tastes like chicken". A guy who's eating another guy to survive would probably even say "Mmm, tastes like chicken" If everything weird that people eat somehow tastes like chicken, then why not say that chicken tastes like weird jungle bugs and other slimy things?
