You\u2019ve got some \u2018splaining to do! It\u2019s National\u00a0I Love Lucy\u00a0Day, commemorating the 66th anniversary (October 15,\u00a01951)\u00a0of the sitcom\u2019s premiere date. Starring\u00a0Lucille Ball, Desi Arnaz, Vivian Vance and William Frawley, the show (which remained the most watched show in the country for four of its six seasons) followed the antics of Lucy Ricardo, her best friend Ethel and their husbands Ricky and Fred. The show remains one of the most beloved of all time and spawned some memorable moments. Here are seven\u00a0of our favorites. 9. Lucy Meets Harpo Marx Lucy\u2019s Harpo Marx impersonation is interrupted by the real pantomime walking through the door\u2014and the two famously act out a hilarious mirror skit. https:\/\/www.youtube.com\/watch?vE4YZKGpe-D0 8. The Barbershop Quartet Always seeking the spotlight, Lucy tries to sing along with a barbershop quartet. They try to silence her, but she gets the last word. https:\/\/www.youtube.com\/watch?vyjnveOPkLq4 7. Lucy Is Enceinte In one of the show\u2019s most touching moments, Lucy reveals to Ricky that she\u2019s pregnant while he\u2019s on stage at the Tropicana. In return, he serenades her with a rendition of \u201cWe\u2019re Having a Baby.\u201d https:\/\/www.youtube.com\/watch?voNZxb0wXZg4 6. Lucy and Superman Trying to throw Ricky Jr. the ultimate birthday party, Lucy tries to hire Superman to make an appearance. He can\u2019t, so Lucy dresses up as the hero instead\u2014but gets stuck outside the window on a ledge. https:\/\/www.youtube.com\/watch?vcsjjkGzixAg 5. I Love Lucy - Pregnancy Cravings This is two parts of two different episodes. In the first one, Lucy dips a dill pickle into a papaya milkshake, in the second, she pours sardines and hot fudge on pistachio ice cream.

In our first Chicks Makin' Bakon, we completely forgot the yeast! Clearly, too much or too little is an issue. https:\/\/www.youtube.com\/watch?vRA3hc4P3qe8 3. Lucy Takes a Dance Challenge Ball shows off her talent for physical comedy in this wacky dance number. https:\/\/www.youtube.com\/watch?vWQGSWBkJW84 2.
