LoL, so two XP shares walk in to a bar. One can see the other but not vice versa. The share that can't see the other says

"Hey other share, I can't see you. Are your permissions set too high?"

the other one replies with

"No that's not it"

so the share asks again,

"Hey other share, are you firewalled?"

to which the 2nd share replies

"Nah man that still isn't it.

then,
"Is your cable plugged in?"
"Yep"
"You on?"
"Yep"

Finally, the fed up share finally says
"Well then what is it!?"

To which the other replies
"Dude, I'm a fridge."

/me waits for the neg pelting
