that reminds me of an episode on the johnny carson show .
an elderly lady was the guest . she had a potato chip that looked like jesus - if i remember correctly .
while she was being distracted , johnny got a potato chip from a bowl under his desk and started to eat it  - CRUNCH ! - the poor lady let out a yelp . 
"oops , sorry ! just having a snack " , said johnny , showing the poor lady her untouched chip . 
 
 
heart attack avoided .
