When the user answers the phone after the second knock down, the Burger seems to not pause and continues to clobber you to death.
This bug has been fixed and is in the most recent build.
However, there is one minor bug that will be addressed soon: if you answer the phone and the Burger is paused at the moment of impact when receiving a punch, this will trigger a continuous damage until you die.
I will make an update when this is resolved.
