Manipulate get_bloginfo() Output

If you want to change the output of anything the get_bloginfo() returns, there’s a couple of filters that make it simple:

(I’m going to leave the practical application brainstorming up to you)

For text:

add_filter( 'bloginfo', 'be_excited', 10, 2 );
function be_excited( $output, $show ) {
    if ( 'name' == $show )
        $output .= ' OMG BBQ!!! FTW';
    return $output;
}

For URLs: change the filter hook to bloginfo_url
