"Last Week Tonight" host John Oliver recently gave a hilarious take on our nation's infrastructure, but he wasn't joking about how seriously we need major upgrades.

Last year, Ray LaHood, former U.S. transportation secretary and congressman noted that due to the lack of funding for repairs and upgrades, “America is a great big pothole.”

One of the funniest quotes from Oliver:

"Dams are amazing. They're the most powerful device we have for holding back liquid ... aside from the idea of using a port-o-potty."
