There's a joke my dad told when we were younger, and we did not realize at the time that it was a joke.
We had a cocker spaniel named Barney and Dad came in from mowing the lawn to say, "I was filling up the lawn mower with gas and I spilled some on the driveway. Barney came over and licked at it."
We all gasped.
"He seemed like he liked it. He started running around the yard, then stopped and fell over."
Oh my gosh! Is he all right?!
"Yeah, he's going to be fine. He just ran out of gas."
