Whoopee Cushion! ( fart )
What better way to break a silence, awkward or not, than with a loud and brutal fart that will make every one in earshot bust up laughing and hold their nose, awaiting a horrible smell that will never arrive.
Burps and Sneeze
What better way to not only confuse an audience than to make your phone burp, sneeze or cough while you keep your mouth closed, but to make people think someone is throwing their voice at you.
This is one of my favorite apps when it comes to massing with people due to the wide variety of noises that it can generate. My favorite is using the snoring feature in classes so that the teachers are frantically scanning the lecture hall to find their next victim to humiliate.
