It's a good one this time.
My local free/swap/for sale page is currently kicking off because someone is trying to flog 200 viagra on there. The conversation so far has gone as follows (word for word)
Seller: 200 GENUINE viagra make me a reasonable offer £££
Commenter 1: You can't sell them, they're prescription only.
Seller: Woo phone the police jeezzuss sort your ed out
Commenter 2: (tags friend) any good for you?
Commenter 1: I know someone that died of a heart attack after taking these.
Friend of commenter 2: I don't need it mate, (girlfriend) can keep it up!
Commenter 3: Are u kidding? Get it off now!
Seller: Everyone fuck off saying get it off!
Commenter 4: Stiff competition hahaha
Commenter 5: Stop drug dealing on this site
Commenter 4: Put them in ur eyes and u will look dead hard hahaha
Commenter 5: You will get arrested
Commenter 4: Are you selling them because ur hard up hahahaha
Commenter 6: (Commenter 5) is a douche. It's not like she's selling heroin or coke get a grip. You look like you've swallowed a few there on your profile pic you've got a stiff neck hahaha.
It's like a soap opera in action. It's actually kind of beautiful 
I'm not sure what the best bit is - Commenter 5 and 6 having their argument out of nowhere, or commenter 4 making stiffy jokes that only he is laughing at 
Someone please tell me IABU for whiling away my Sunday night laughing at these fine examples of humanity, when I could be doing something much more productive
