... Cat ruined my homework. 
I'm flashing the #EEPROM on a Raspberry Pi #CM4. It's a suuuuper slow process that, happens over USB 2.0. Some 10 minutes into the copy, cat jumps onto the couch to say hello... Starts licking me, then she licks the CM4 module and carrier board. Luckily this is all 5V, but an error pops up in my console. 
I lose another 15 minutes trying to get the flashing working again, set the computer down, and immediately distract her with treats. 
I'm in a completely different room from the computer flashing the module, just so she isn't tempted to lick it again.
