Can be this so it would be $nick's instead of $nick 's

if (%cookie == 4) .timer 1 2 msg $chan  The cookie flies out of $nick $+ 's hands, and falls right into $me 's mouth.

Or if you wanted Regex, I added some stuff

(07:34:36) <@Dean-> @cookie
(07:34:37) %[eH] Dean- steps up to the cookie...
(07:34:39) <%[eH]> Dean- gobbles up the cookie.
(07:34:41) <@Dean-> .cookie
(07:34:42) %[eH] Dean- steps up to the cookie...
(07:34:43) <%[eH]> Dean- has a bad aim of where his/her mouth is, and gets some crumbs in his/her eye.
(07:34:44) <@Dean-> !cookie
(07:34:45) * %[eH] Dean- steps up to the cookie...
(07:34:47) <%[eH]> Dean- gets bullied into giving the cookie to [eH] .
