At least that slide is fun! The colorful tube water slide was really, really lame. Everyone gets stuck partway down and you have to pull yourself along for a while before you can get to the bottom. It just needs to be steeper.
My two sons-in-law agreed that it was terrible, so they told my two daughters, "That's awesome! You have to try it!" When my daughters got off of it, they said, "YOU are a LIAR!" while all of them laughed.
It was so obvious that it was terrible that it was hilarious to suggest that it was great.
