The host of CNBC's market analysis TV show " Mad Money" has made a name for himself with his boisterous personality. In his heyday, he threw stuff around like a toddler having a temper tantrum.

Things must be pretty bad for a guy whose advice has become so unpopular in some circles that there's a whole exchange traded fund dedicated to betting against his stock picks.

Cramer was a big fan of Meta- formerly known as Facebook. Despite the company's plunge in stock price this year, he's been an ardent supporter of the company.

Its stock plummeted on Thursday. Cramer was vulnerable on that day.

I made a mistake here, let me tell you that. He said that he was wrong. Cramer said he trusted the management team. That was not the right thing to do. I apologized for the arrogance here.

His co host replied awkwardly.

Trust No One

Cramer also apologized for his actions. He said that his main mistake was not trusting himself.

I don't know what I got wrong. He said that he did not trust them. He said he regretted it.

He said he tries to help people every day. I didn't help anyone. I own that as well.

If we were all in on the train wreck that is Facebook, we would cry too.

Zuck's crusade has caused his company the biggest single day market value plummet in history of over $250 billion.

It's his employees that will suffer the most for his stubbornness, with mass layoffs imminent and interns getting their internship revoked.

If he had any shame, he should be crying on TV.

There is more on Facebook.
