Haha, don't worry, I have a cousin that can take an engine apart in minutes. Only problem is that he has never been able to put one back together. Not without having left over parts that is
He once asked me to go buy 5 spark plugs so he could do a tune up on my 6 cylinder car 
my best friends brother is one of those guys that can/will get a box. as he disassembles things to remove an engine from a car, he tosses everything in the box.
when he reassembles everything, he's never short anything, and never has left over parts. i tend to put things in a sort of order of removal, so i can remember where they go when i do this.
i also saw him swap a 351 in a neighbors pickup. out, in, and running in less than 4 hours.
