This:

    $,="\t"; print readlines.map{|r| s=r.split; [s[0].to_i,r]}\
    .max{|a,b| a[0]<=>b[0]}

It's a ruby one-liner that prints the largest first field and the lines that contains that field.

Being too clever for your own good and writing wonderfully elegant code that randomly breaks on some other engineer who doesn't know you long after you have left the company. Surprise tire fire!
