[jQuery] Array of numbers in contains()

[bsuttis]

Hi, I'm appending a word to a number like so:

$(".field-item:contains('25')").append(': Extreme');

My question is, given that the numbers 20-25 all should append
'Extreme', is there an easier way than doing the following?

$(".field-item:contains('25')").append(': Extreme');
$(".field-item:contains('24')").append(': Extreme');
...
$(".field-item:contains('21')").append(': Extreme');
$(".field-item:contains('20)").append('': Extreme');

Maybe using an array or range function? Though I may be thinking too
much like php.
