Okay.
P:\test>perl -ne"$p=tell ARGV; print if /Larry|Robb/ and not scalar <>
+ =~ /Larry|Robb/; seek ARGV, $p, 0; " logfile
1056128833340 Robb 2003-06-20 665 **
1055439973653 Larry 2003-06-16 815 **
Usual caveat: 's instead of "s on *nix.
Update: Added code to bottle out as soon as we've printed the two records.
perl -ne"BEGIN{$C=0}$p=tell ARGV; ++$c, print if /Larry|Robb/ and not
+scalar <> =~ /Larry|Robb/; seek ARGV, $p, 0; exit if $c==2 " logfile
or golfed a bit
perl -ne"BEGIN{$C=0}$p=tell ARGV;/Larry|Robb/&<>!~/Larry|Robb/and++$c,
+print;seek ARGV,$p,0;$c==2&&exit" logfile

If I understand your problem, I can solve it! Of course, the same can be said for you.
