My psycho hobby

wait wait, ok lets start this over...

i open the bottle of coke, right? now i put 'that you screw on so the fucking thing wont spill coke on you' and it has a blue thing in it?

since when do you screw anything into a bottle of coke?
 
I know what hes talking about...But do you collect the lid, or the weird plastic dealie-bob underneath the lid, or are you talking about that peice of plastic that seals the lid before you open it..(you know that ring of plastic?) WHich is it??
