On a really bad day, sometimes the thing we most need is someone else's perspective to help us laugh about it all. And who better to remind us of that than an adorable, laughing baby? This video has gone viral after Alyssa Milano tweeted it out to her followers and with good reason. It's so very, very precious.

The story is this: Dad, Marcus McArthur, 33, had received yet another rejection letter for a professorship. He ripped it in half and his 10-month-old son, Micah, started to laugh. And laugh and laugh and laugh ... The video went viral and the rest is history.

Here is baby Micah laughing in his little pink sleeper:

This should cure what ails you. After all, aren't there times when you're annoyed -- someone was rude to you, work went badly, you had the commute from hell, whatever the reason -- and your children do something so adorable you wish you could bottle up their enthusiasm and happiness?

Well, now you can! Micah makes me want another baby so badly. His little laugh is so sweet and reminds us all that even on our worst, most hideous days, someone out there is having a great time and enjoying life.

It's infectious!
