I agree, Gummo. Slacker could've done it like so:

on $*:text:/^!(about)?(poke)\b/iS:#:{
  if ($2 ison #) && ($regml(1) == poke) { describe # pokes $2 }
  if ($regml(1) == about) {
    .notice $nick This script was made by Matt.
    .notice $nick IRC vHost, Matt@Hiding.My.Identity.From.You.Stalkers
    .notice $nick Do not reproduce without my explicit permission.
  }
}
