Oceans 11?

Our friend Jeff jokes about Oceans 11, Oceans 12, Oceans 13, Oceans 14, The Oceans 11 DVD Club, and anything of the sorts. One day, he IMed my sister, who left her AIM up, asking her how many Oceans 11 she owned.

hi. i just got off the phone with you and went to check my messages on my computer before bed. and there was this instant message from jeff and it said, "how many ocean 11's do you own." so now i'm really confused because i think chloe's IMs still come up on my computer and i'm pretty sure jeff wasn't asking me. don't call me now because i'm going right to bed. but, huh?
