A woman walks into her doctor's office and says, "Doctor, I need to
lose weight fast." And the doctor says, "Instead of putting food in
your mouth, try putting it up your butt."

Two months later she comes in and says, "Doctor, it's a dream come
true. I'm half the size I was." But the doctor notices that she is
bouncing up and down up and down... and he asks, "But where did you
get this twitch?" The woman replies, "I don't have a nervous twitch,
I'm chewing bubble gum."
