1. Marines carry brief cases.
2. Soldiers carry attaché cases.
3. The Navy carries the load.
I could add, "and bugs out like at Guadalcanal"...but I won't....
Judging from many I've seen, this is true. They must be fed well during those long voyages from home. ;-)
A young kid is running around the mall, screwing around and sees a young sailor, home on leave from basic training, walking about the mall in his cracker-jack outfit. The kid runs up to the squid, er, uh, I mean sailor and says, "Hey, ain't you one of those sailors that protect our way of life, sail the seven seas and keeps America free?"
The sailor beams with pride and says, "Why yes, son, I am. Here, you can wear my hat." The sailor then hands his hat over to the kid.
The kid happily puts the hat on and runs about the mall, frolicking to and fro. Eventually, the kid needs to relief himself so he goes to the head (latrine for you illiterate folks out there) and sees a Marine Lance Corporal (God loves LCpl's) in his service Alpha's, laying on the deck next to the toilet, obviously drunk and in a serious state of dishevel.
Sternly, the kid asks the Marine, "Hey, ain't you one of those Marines who runs around town causing hate and discontent, starting bar fights and stealing people's daughters?"
The Marine slowly opens one eye and tells the kid "Suck my $%&^, kid!"
Confused, the kid replies, "But I'm only wearing a sailors hat!"
