Casey said that the clocks enjoy living in the humans homes and watching all the silly things they do. I guess that is something they have in common with us dogs because I also find the silly human antics entertaining. Alarm clocks are the mean members of the clock dynasty because they get to wake humans up from a sound sleep, and they enjoy their work.
I will leave you with this link so that you can see a bunch of clocks. Even I think some of them are very pretty, and we dogs don't usually notice that sort of thing.
