Thought this was hilarious:

To fix this, we suggest adopting the Attenuation Removal Machine or iARM to make all of your calls. Our lab tests have proven, using a plastic robot hand will not only provide better reception and faster data streaming, it will stop people from sitting next to you on planes and buses.
We hope you love the iARM as much as we do.
