That joke is universal; just substitute different hats. I first heard it with the parts reversed. Although really, both sides lose. I mean one service may suck dick, but the other one is soliciting a BJ from a small boy. Who's really coming out on top there?
ARMY actually stands for Ain't Ready for the Marines Yet.
USMC. The first four letters in "MUSCle"; none of the letters in "brain."
USMC also stands for U Signed the Motherfucking Contract.
Another joke, again on or about the Corps.
A hard-charging NCO dies in battle. He hasn't lived a virtuous life, so St. Peter sends him straight to hell. He's bummed out, so he's sent to one of hell's counselors.
The counselor tells him, "Hell's really not that bad. You like drinking?"
The NCO says,"I'm a Marine, of course I like drinking!"
"Well, on Mondays, after we get done in the lake of fire, it's all-you-can-drink night. Johnny Walker Blue Label, the best brews, the finest wines, whatever you want. ANd we can all drive back drunk...'cause we're already dead! Say...you like smoking?"
The Marine says,"I loved a good cigar."
"Well, Tuesday nights, the smoking lamp is lighted, and we break out the best Cubans. And who cares about cancer...we're dead! You like gambling?"
"Damn straight. I went to Vegas every time I went to CAX."
"Wednesdays we have gambling night. Texas hold-em, Blackjack, everything. And if you go broke, what'll they do to ya...send you to hell? How about fighting?"
The Marine says,"I loved a good brawl when I was in the Corps."
"Thursdays it's like UFC around here. Bare-knuckle boxing, wrestling, whatever. And if you get hurt--who cares? You're dead"
"Sounds great," said the Marine.
"Say...are you gay, by chance"
"Of course not," said the Marine,"I'm a US Marine, for crissakes."
"Well, you're not gonna like Fridays..."
