Concours Lépine (Foire de Paris)

If you're in Paris, this is the last day you can visit La foire de Paris (the Paris Fair), probably the largest in France. The greatest part - in my opinion - is the Concours Lepine (named after the guy who created it), a competition for inventors. Walking down the aisle of this part of the fair is like watching the Shopping Channel all day, only 100 times better! Frankly, who would have thought of inventing this "Champagne cork stopper" that prevents corks from hurting people when they pop out of the bottle?! Il Signore Michele Procopio (who is actually Italian) did, and he sells them for 25 € each. Pretty cheap!
