“What do you call a chef under stress?”/“A pressure cooker.”

There are several jokes about pressure cookers and slow cookers. This pressure cooker joke is from at least 2002:
 
Q: What chef thrives under stress?
A: A pressure cooker.
 
Several politically incorrect jokes have been made about slow cookers, such as this one posted on Twitter on Novembe 2, 2011:
 
“Q) What do you call a chef with Downs Syndrome? A) a slow cooker.”
 
A less offensive “slow cooker” joke was posted on Twitter on August 29, 2014:
