Tonight, "The Big Bang Theory" season 7 episode 17 will air on CBS, and now fans can watch the live stream online.

In tonight's episode, "Things turn rocky between Sheldon and Wolowitz after a barrage of insults, and Bernadette steps in to mediate a peace. Meanwhile, Penny is offered a movie role that may prove embarrassing, and Raj asks Amy to play Cyrano de Bergerac and pen a note to a woman on his behalf."

For CBS, there is a live stream which can be accessed here and here (depending on your region, one may be accessible over the other), and through that, fans can watch "The Big Bang Theory" season 7 episode 17 live stream.

There are a lot of fake channels solely for the purpose of luring viewers with ads, but here is how you can avoid any potential hiccups with pop-ups and ads.

--Do not download anything that is suggested.

--For every ad, there is an "X" button. It is typically in a corner or out of the way so it is hard to see. Sometimes ads try to fool you by giving you a fake "X" graphic which leads you to an ad. Do not be discouraged when this happens, the real "X" button is there somewhere.

--Multiple ads will pop and it takes a little bit to clear out each and every ad. Even then, pop-ups will occur as you clear the ads. Do not listen to any of these ads or pop-ups and clear them right away.

--This "The Big Bang Theory" season 7 episode 17 live stream will have recurring ads that pop up every once in a while. If this is the only way you can view "The Big Bang Theory" season 7 episode 17, do not be deterred and the live streaming will work once the ads disappear.

Be sure to check out "The Big Bang Theory" tonight on CBS at 8:00pm EST!
