daymond john*What started out as a good time catching up turned into a lesson learned for “Shark Tank” judge Daymond John.

The FUBU clothing line founder sought advice from his Facebook followers during a reunion with his ex-girlfriend over drinks. According to John, “The first hour of catching up was fun.

“The drinks have now settled in and she has been talking my ear off for 3 hrs!! She is also starting to make the subtle hints about having a lil after party, Wink wink! Nothing could be further from my mind! . . . What do you think I should do???,” he wrote not too long ago on his Facebook wall. “

John received 1,500 bits of advice on how to deal with his ex, including one suggestion to give his “Shark Tank” send-off: “For that reason, I’m out.”

As it turned out, John didn’t have to do anything at all as his ex ended up leaving on her own. Sort of.

“I came out of the bathroom, her phone was going crazy and she flew out of the restaurant like a bat out of hell,” the businessman wrote. “I found out later that her boyfriend hopped in his car in his pajamas to come and snatch her up.”

As with any experience, a valuable lesson was learned. In John’s case, one of the things he took away was the following:

“Don’t meet up with someone who has been drinking all night when you’re dead sober.”

Case closed.
