Remember The Big Bang Theory? That brilliantly written and produced sitcom that aired for TWELVE seasons and brought us nonstop laughter and joy?!
Perhaps your favorite moment was when Leonard got down on one knee and popped the question to Penny...
...or early on in Season 2 when Sheldon's friendly prank backfired.
What about that equally hilarious and sweet time Leonard found "Shelly" in the ball pit having a major breakdown?!
Remember that epic girls-versus-boys game night when Penny and Amy swept the competition?
But one of our absolute favorite moments is when Sheldon thought he might've had a brain parasite but he'd actually just been bitten by the love bug.
Speaking of love, Leonard and Penny's imperfectly perfect Vegas wedding was the happiest day of many of our lives.
