Almost as much embarrassing as the Bitcoin revert IMHO – https://en.bitcoin.it/wiki/Value_overflow_incident

Eh, they were very different. From a technical perspective I'm not sure which bug is worse (FWIW the Bitcoin one happened 1 year after it launched and 5 years before Ethereum launched), but the justification for forking Ethereum was weaker and more controversial.
Ethereum was forked to revert the loss of funds (about 3% the current supply of ETH I think) of users of a specific (but popular) buggy contract. Ethereum itself would have survived without the fork.
The Bitcoin bug enabled an attacker to create ~184 billion Bitcoin, resulting in something like 50,000% inflation. Not reverting that would absolutely have killed Bitcoin.
