The one I know of is the one that generated a few billion coins. That was a bug in the client, and the block was invalidated.

"Strange transactions" are transactions containing inputs/outputs with unusual scripts. There are no "strange blocks".

Can you expand on this? The one I am looking at is at the bottom of blockexplorer.com currently. It claims that 3 blocks all had different hash values and slightly different (albeit very low) number of BTC sent...

What happened there?

Someone filled those transactions with "OP_CHECKSIG" commands in a potential denial of service attack due to the additional work incurred by the network to process them (https://en.bitcoin.it/wiki/Incidents#OP_CHECKSIG_abuse), back in July.  An update to BitCoin fixed the vulnerability without needing a fork.

Always well spoken eMansipater.

Thank you for the clarification.
