Yes, it has a smidgen of polarity, but let's play the "How Nonpolar Is Dichloromethane?" game...
It's SO NONPOLAR, it's completely insoluble in water.
It's SO NONPOLAR, you can use it in place of hexane or pet ether to extract non-salt organic reaction products from aqueous solution.
It's SO NONPOLAR, its boiling point is marginally above room temperature (like diethyl ether, hexane, or pet ether).
Polarity is on kind of a scale. If hexane is a 0 and water is a 10, dichloromethane would be like a 1.
Okay, here are a few more. YMBACM If...

... when they do that, you don't mind because everything is non-toxic.
... but they DON'T want you to wash dishes on camping trips with limited water because you can't stop rinsing everything three times.
... when the biologists are autoclaving their petri dishes, and the odor of baked refrigerator-experiments-gone-wrong is making everybody around you vomit, you just laugh because any day you can smell something and it doesn't kill you, it's a good day.
