Three O6s walk into a bar...

One is a USMC Colonel, the second is a US Army Colonel, the third is a US Navy Captain....

The Navy Captain excuses himself to the restroom and the other two start talking.
The Army Colonel mentions Command and staff college.
The Marine Colonel asks what he learned there, to which the Army Colonel replies "well...first we learned about logic".
The Marine Colonel looks vexed and asks "what the hell is that??"
The Army Colonel thinks a second, and says "well, Ill give you an example. Do you have a lawnmower?"
The Marine O answers "yes"
The Army O says "From that I can deduce that you probably have a house with a yard"
The Marine O Answes "Yes"
The Army O says "From that I can deduce that you are probably married"
The Marine O answers "Yes"
The Army O says from that I can deduce that you are a straight man"
The Marine answers "Oorah"

Right then the Navy Captain returns and asks "what have you guys been talking about?"
The Marine Colonel jumps right in and says "Logic"
The Navy Captain asks "What the hell is that?"
The Marine puffs out his chest and says "Let me give you an example. Do you have a lawnmower?"
The Navy Captain answers "No"
The Marine grins and says "You're gay"

and all the enlisted walk out.

And start trying to determine which branch had the most guts. The Army Colonel says "the army of course" looks to his SPC aid "see that hmmwv coming down the street, go stop it" the SPC runs too the road and tries to strop it with his bare hands... He gets ran over. "now thats guts" says the Colonel. Ha Says the USMC Colonel, he looks to his CPL aid "see that Abrams coming down the road go stop it". The CPL runs to the road and tries to stop it with his bare hands.... He gets ran over. "Now that's guts" says the USMC Colonel. The Captain looks around for a second and beckons for them to walk out side. He looks up to the sailor in the watch tower above the bar. "Hey sailor jump out of that tower". The sailor looks down over the edge and looks at the Captain "Sir are you crazy, go (insert your favorite term) yourself". The Captain looks at the other two, "now that's guts".
