Set the values in variables, then call them with the alias.
Code:
if ($nick == Nick1) { noop $tip($nick,Join,$nick joined $chan,5,,,echo,$wid) | set %user.nick $nick | set %user.join $chan | user.joined }
alias user.joined { .echo -q $input(%user.nick joined %user.join,wo,Alert) }

Untested, but i hope it working..

if ($me != tired) { return } | else { echo -a Get a pot of coffee now $+($me,.) }
