print "$Robert has canned ${name}'s sorry butt\n";

The apostrophe is the old-style package separator, still supported, so $name's is indeed equivalent to $name::s. By putting the curlies in there, you tell Perl exactly which part of the string to consider part of the variable name, and which part to consider a literal value.
