Version of Gary Larson's "What we say to dogs" cartoon
In both panels a man is pointing at a dog, talking to it

What we say to audiences:
"I can answer questions if there's something you urgently don't understand. I'd prefer that you ask questions rather than just sit there being confused"

What they hear"
"blah blah QUESTIONS blah 
blah blah blah blah blah 
blah ASK QUESTIONS blah 
blah blah blah blah ..."

It is an iron law of academic talks that if a speaker says they're willing to take questions "if there's something you don't understand" then the session will immediately begin to derail into a free-for-all in which everyone feels an urge to express every random thought that pops into their head
