If you're driving 80 miles an hour, how long would it take you to go 80 miles?  The answer is . . . AN HOUR.  But some girl in Northern Ireland asked her sister, and she could NOT wrap her head around it.



Then their mom gets in on it, and yells at her in a heavy accent for being a MORON.



(Search for "Family Discussion in Belfast."  She seems to figure it out around 2:11.  WARNING:  The mom tosses around A LOT of profanity.)



(There's another video where a guy driving posed the same question to his wife, and she goes through a REALLY long and complicated answer.  Then he tells her the right answer, and she STILL argues with him.



(It's from 2011, so we'll overlook his illegal 'selfie-video-while-driving' thing.  Also, both girls in both videos are blond, and somewhat attractive.  Just making an observation . . .)
