<input type='submit' value='are you cool?' onClick="alert('*shakes 8-ball* Try again later.');">

<input type='submit' value='are you cool?' onClick="alert('*shakes 8-ball* Sss, just a little longer....');">

<input type='submit' value='are you cool?' onClick="alert('*shakes 8-ball* Ohhh, you waited too long. Come back next week.');">
