The Football fight scene where our hero takes on Ming's guards by playing quarterback. The whole sequence is a winner from Dale playing cheerleader to BRIAN BLESSED whacking random guards on the head with his staff while their backs are turned to Ming's priceless remark about Klytus' troops:
Ming: Klytus! Are your men on the right pills? Maybe you should execute their trainer!
Dale's escape from Ming's chambers. The bit with the shoes, the unnecessary cartwheel - pure She-Fu.
Barin and Zarkov are chained up in a dungeon.
Barin: Tell me more about this man, "Houdini".
Made even funnier by "LONG LIVE FLASH!" being randomly burned into the wall behind them.
At Ming's wedding, ships fly two banners in the background. The first says "All creatures shall make merry". The second says "Under pain of death".
Long live Flash! You've saved your Earth. Have a nice day.
