Sean Payton was hit with all the hard questions during a conference call with reporters on Wednesday ... and like a true pro, he had the answers to EVERYTHING -- even a pesky stain!!!
"Let me ask you a question," the reporter began -- not knowing everyone in the call could hear him -- "I spilled mustard on my suit..."
And, before the reporter was able to finish his thought -- or realize he wasn't muted -- the New Orleans Saints coach came through with some sound advice!!
"Generally with mustard, I'd use warm water," Payton said.
"I wanna use warm water, I don't wanna wipe it, I want to blot it and I want to treat it twice."
Of course, the embarrassed reporter quickly apologized for the hilarious blunder -- apologizing for having his mic on -- but Payton continued helping with his problem.
"You can't put it in the dryer on hot or it's going to be stained. If none of those things are working, seek outside help."
Great advice from Coach ... and good luck with the suit, guy!!
