Riding the Roomba

An expression of such utter boredom that effortless joyriding on a robot seems the last thing left to do.
Pretending you are a shark chasing prey is meant to add some entertainment even though you know you just look sad.

When:
You are a smart cat who has matured...
The mystery of the red dot has been solved...
Harassing the dog isn't as entertaining as it once was...
Life is so boring that even catnip doesn't do it for you anymore...
What can you do?
You can always Ride the Roomba.
