Rockets Twitter, what are you doing?

The Rockets just won their second playoff series in the last 18 years, eliminating the Mavericks in five games.

Safe to say Houston was excited as Game 5 neared its end.

A little too excited.

Yikes.

The Mavericks responded:

@HoustonRockets Not very classy but we still wish you guys the best of luck in the next round.

And the Rockets apologized.

Our Tweet earlier was in very poor taste & not indicative of the respect we have for the @dallasmavs & their fans. We sincerely apologize.
