This is an example of what you could do:

; Usage: /ping <nick>

Code:
alias ping set -u100 %ping $+ $$1 $ticks | ctcp $1 ping
[color:red]  [/color] 
on *:ctcpreply:ping *:{
  if ($($+(%,ping,$nick),2)) {
    haltdef
    echo -atc ctcp [ $+ $nick PING reply]: $calc(($ticks - $v1)/1000) $+ secs
    unset %ping [ $+ [ $nick ] ]
  }
}

Gone.
