A soldier, a Marine, and an airman are getting ready for bed one night.
The soldier opens his tent and sees a scorpion crawling on the floor. Unfazed, he crushes the scorpion, crawls into bed, and falls asleep.
The Marine opens his tent and he too finds a scorpion. He quickly draws his knife, removes the scorpion's stinger, and swallows it whole. Satisfied with his snack, he quickly falls asleep.
The airman opens his tent and also finds a scorpion inside. He immediately shuts the tent, picks up the phone and makes a call. A voice answers on the other end and the airman demands, "Why the hell is there a tent in my hotel room?"
