Lol. Omg, we, by this I mean the americans, used to be way worse with the offtopic talk.
I hope Selena does something interesting again soon though so that we can talk about her again.
If you're constantly going off topic because you simply want to increase your post count and you have nothing to say about the artist in question, that's when problems arise. Or if all you do is post "hi" and "bye", then your presence in the thread doesn't add anything of value.
Because Adam Sandler is the main character and Andy Samberg is like his partner in crime. I doubt they'll bring 3 people to promote a movie. Unless he uses Selena instead of Andy which is much better.
