Commedian Jim Gaffigan has brought this issue to light during his stand up routines. In particular, Gaffigan goes into detail about staying up late to watch a Growing Pains marathon. This seems like a great idea at the time, but upon waking up...Growing Pains wasn't such a good idea afterall.
So essentially The Growing Pains Paradox is staying up late for anything that seems like a good idea in the evening. However, due to the lack of sleep you regret the decision in the morning.
