I just tried the code above and it only prints the first word (update: on each line) that contains an exclamation point.

#!/perl
use warnings;
use strict;

while(<DATA>){
    #print map {"$_\n"} grep{/!/} split;
    /(\w*!\w*)/g && print "$1\n";
}

__DATA__
 Mary had a little lamb! ,
 whose fleece! was white! as snow.

 And everywhere! that Mary went,
 the lamb was sure! to go.

Produces this:

lamb!
fleece!
everywhere!
sure!

Oops - try

while (/(\w*!\w*)/g) {
   print "$1\n";
}
