#1 I saw popeye and his pappy swaying in there hammocks when I was a kid. (Thats also why I like spinach). from then on, I have wanted to sleep a-swingin.
#2 There are a lot of rattle snakes where I live.
#3 I sat on an ant pile when I was a kid, thinking it looked like a nice stool. The girl I was talking to screamed and ran away. I looked around, What?
I looked down, and I was completely covered in a swarm of texas fire ants. After that I was never the same about crawly bugs. I like sleeping in a hammock knowing that Im not sleeping with the ants that forever torment my soul with their black plague of tickling paranoia.
#4 Because you fall through a cloud if you try to lay on one. So the next best thing is a hammock.
