It's a fact that nothing gets an NBA team and its fans more pumped up for a huge game than "inspirational" videos from celebrities. Right?

…Right?

OK, so maybe not, but don't tell the Celtics that.

The C's posted three videos to their Twitter page on Thursday afternoon, getting the help from some of their celebrity fans as they put together some videos to pump up the team. Maria Menounos, Michael Chiklis and Dane Cook all got in on the action.

The idea is so-so at best, and the finished product is, well, kind of awkward.

See all of them below.

Important note: If you're listening with headphones, turn them down a little bit before watching. Trust us.
