```js
var Emitter = require('easy-emitter')
Emitter.call(buddy) // become emitter
buddy.on('kick', function onKick(){
console.log('ouch~')
if (++this.kickCount >= 5) {
this.off('kick', onKick)
console.log('you are dead~')
}
})
_.times(100, function(){ buddy.emit('kick') })
```
```js
// easy-emitter.js loads
var Emitter = window.EasyEmitter
```
