It all went down on a Southwest flight from Burbank to Las Vegas Thursday during the aircraft's final descent. Flav grabbed the intercom mic -- ya know, the thing pilots give important safety information on -- and addressed the entire plane.
The best part ... Flav capitalized on the opportunity for some free advertising and plugged his Las Vegas restaurant -- Flavor Flav's House of Flavor -- and then just listed everything they sell ... like fried chicken and waffles.
He then lead the entire plane in a chant of "Flavaaa Flaaaaaav."
Where's an air marshall when you need one?
