It was a very special occasion as the entire audience was filled with men and women in uniform, in honor of New York's 30th Fleet Week. So, Fallon and Rucker wanted to show their support.
The two parodied the original song with a new version titled "Only Wanna Thank the Troops," in which Fallon and Rucker sang, "Army, Coast Guard, Air Force, and Marines, here's to the Navy for protecting all our seas. You serve with bravery, you serve with style, you serve with six-pack abs, I can barely run a mile. Well, we owe it all to you. I only wanna thank the troops."
The all-military Fleet Week audience totally enjoyed the performance as they stood up, danced along and laughed to more hilarious lyrics like, "You fight for freedom all across the land. I hope while you are here you have a one-night stand. Let loose in New York and make it great. Hope when your captain pukes you get it all on tape. Just don't post it on YouTube. I only wanna thank the troops."
