No matter what you achieve in life, no matter what you do, don't ever forget to call you mom. Because if you do, your sibling will find the most inappropriate moment to point that out.

Just like CNN news anchor Chris Cuomo did. 

He was on air with his brother Andrew Cuomo, who happens to be the governor of New York.

The two were trying to be really professional, discussing potential lock down New York can face in the wake of coronavirus outbreak.

And then Chris mentioned the word 'curfew'. 

That unexpectedly triggered Andrew, who made this snarky remark:

I don’t like the word ‘curfew.’ Dad tried to have a curfew for me, I never got past the resentment. But I do believe you’ll see more heightening if the numbers don’t slow.

Not the one to take that insult, Chris retaliated by hitting him where it hurts the most:

Well, I don't believe in rules. I appreciate you coming on this show, I love you, I’m proud of what you’re doing. I know you’re working hard for your state, but no matter how hard you’re working, there’s always time to call mom. She wants to hear from you, just so you know.

Following which, they hilariously started discussing who is their mom's favourite son.

Andrew: BTW, mom said I was her favourite. Good news is, she said you are her second favourite.

Chris: We both know neither of us are mom's first or second favourites in the family. I can't believe you lied to my audience.

In the end, there was a 'I am looking at you' gesture from Andrew which almost killed me. 

This just makes me think it's that my brother and I are not famous people. I can totally picture us doing this.
