Here's a transcription, including all weird grammar and capitalization:
Did you KNOW:
There's this so called grown up not sure if its a man or woman because it reminds me of "Pat" from Saturday night live. "Pat" was a disgusting character that I never though I'd have the displeasure to meet anyone like it but there's someone that lives in my building that behaves as such. Anyway the thing in the building trollups about so rude & disgracefully so. Doing everything to disturb the other tenants like fake snoring while lying on the floor! No grown ups that's intelligent would ever stoop to such retarded behavior. The overgrown thing even drags chairs & furniture all times of the morning & night just to disrupt an otherwise peaceful environment. The bafoon even follows the neighboring tenant as it can hear her walk from room to room like some sort of imbred shithead looking for its mothers nipple to play with while she changed his soiled undersized Depends diaper. Craziness! I KNOW I KNOW - BUT DID U?! the thing should 302 itself... don't you think?!
What? I mean... what?
The note was left unsigned, but it's pretty easy to guess who wrote it. There are only three apartments in the house. One of them is mine. One is my landlord's, and I'm fairly certain he wouldn't write this.
Obviously I need to have a chat with the landlord and this individual.
You can bet I'll be double checking that I lock the door at night. The person who wrote this is clearly not completely well.
