An Antartian woman came into a bar and asked the bartender for a drink. Then she started to yell, "Yeah!" "Yeah!" Then five more Antartians came in and started to do the same thing. Then three more Antartians came in and one of them had a Barney puzzle. The bartender asked one of them, "Why are you yelling 'yeah yeah!'?" Then one responded, "We did this puzzle in three hours and it says 2-3 years."
