Sometimes easy does it. Well, what do mosquitoes prevent you from? A good night's sleep. What do you do? Put a mosquito net (well, not always but that was the idea at base). The ad above joins "l'utile a l'agreable" as the French say (the useful to the enjoyable). It says "nemo" (sleep) and "nemo-usiye" (mosquito net). Smash! (a pun, in case you did not get it because that's the product's name!).
See? Told you easy does it. For reference, Smash Plus had a good ad prior (here).
