A TV ad commercial for a "Loud 'n Clear" hearing aid plays relentlessly.
One of the bits shows a lady playing BINGO, she asks her friend what number was just called. "B3" is the response. "Darn, I had it". According to the accepted rules of BINGO, doesn't she still have it??
Another bit shows a stealthy hunter holding a high powered rifle in the woods. The voice over guy say "You can hear game before they hear you". If he shoots, but forgets to turn off the device, does his head explode??
Just wondering..........
