Throughout its seven seasons, 30 Rock has made us laugh and cry (though thankfully not out of our mouths). But most of all, 30 Rock has cracked eggs of wisdom all over us. To honor the show that's taught us so much, we've compiled its thirteen most important life lessons, one for each episode in the final season.

So though 30 Rock might be leaving, never stop asking yourself: WWLLD? (Or just eat something. It's pretty much the same thing.)
