Yup, it's really a good piece--had me laughing almost from the start. Stray word here: so he cooked at all day and night

Actually there's a bit of a syntax/logic issue here, as well:

he taught me to cook
everything except the Chinese specials
so he could take Sundays off to go
to the Chinatown whores and fuck

I think what you mean to say is

he taught me to cook
so he could take Sundays off to go
to the Chinatown whores and fuck

The line "everything except the Chinese specials" you might want to wedge in parenthetically.
