How do you turn off the sound that the blocks make???

How do you turn off the sound the blockes make, when you join them,its irritating cause I was trying to watch life of brain montypython and all i could hear was click click click...

plz help

You can't... If you're trying to watch a movie, then you're not concentrating on programming.

I suggest you watch the movie, then do some programming...

Actually, you probably should do the programming first, and when you're done, THEN watch the movie.
