Yes, "the centipede effect": https://en.wikipedia.org/wiki/The_Centipede%27s_Dilemma

[sebmellen]

What a great poem:

“A centipede was happy – quite!

Until a toad in fun

Said, "Pray, which leg moves after which?"

This raised her doubts to such a pitch,

She fell exhausted in the ditch

Not knowing how to run.“
