You can also do it this way:

on *:TEXT:*:#: {
  tokenize 32 $strip($1-)
  if ($1 == !8ball) {
    msg $chan Original question: $2- And the answer is:
    var %x = No!|Yes!|Of course|Have you gone mad?! I think you have|$&
      How should I know? Its not like I'm magic|Heck no!|Maybe... yeah|Why should I tell you?|$&
      If I say yes will you be quiet?|Yes... that will be 30 dollars|How should I say this? Um... no
    msg $chan $gettok(%x,$rand(1,$numtok(%x,124)),124)
  }
}
