The limit is on the allowed amount of fun.

The bigger joke is that people think Mike is a stand-in for me, but Mike has never raised his voice to express himself.

Once again, this comic is semi-autobiographical. I can invoke Murphy's here because I've been saying that due to all the rain this summer, I haven't had to top off the pool (or water the garden as much), so the water bill should go down. And now there's a week of Sun ahead of us, and I'm topping off the pool. With cold water. That likely won't warm up too quickly.
