Rewritten version with only 7 lines I wrote this morning instead of working:

(lambda t,d,r,i,s:(lambda s,r=r.match:(s.connect(('irc.rozznet.net',6667)),s.
send('USER h h h h%sNICK hhh'%d+d),[(t.__setitem__(slice(None),a[1]),[s.send(y(
*r(x,a[0]).groups())+d)for x,y in((':.*? 002','JOIN #test'.strip),('PI(NG.*)',
'PO'.__add__),(':.*? (PRIVMSG .*? :)!(.*)',lambda c,m:(lambda x:x and c+x or'')
