My Amazon Echo's name is Echo because my parrot always says "Alexa" and then he turns on and off the lights and it's really funny so we had to change the name of it.

[@susanna1021]

My Alexa TOTALLY responded to "Who let the Dogs Out" - 5 a.m. in the morning it BLARED! LOLOL

[@haninabritanico9912]

Jimmy: "So the prank is everyone in the family gets the flu?"

[@ThermicYT]

Jimmy "And this was simple to build?"

If somebody actually ends up getting 500 dollars worth of pool noodles that would make my life.

Mark Rober and his nephews are the best.
