NASCAR has a lot of history in its 63 years.
Most of it has been a grand ride.
There's been spectacular wins, amazing stories behind the wins and a colorful cast of characters from the sport's inception in 1948 to today.
Along the way, the sport has also been peppered with some moments that NASCAR would like to forget.
Some of the moments and stories in this list are embarrassing for different reasons.
A handful of them are funny, but cringe-worthy. They're like the moments in a comedy film where you're looking around the theater wondering if it's OK to laugh.
Some are moments when someone got the better of NASCAR by outsmarting the sport (although ultimately almost always being caught).
Others are just a black eye on the sport.
Some are even not necessarily embarrassing to the sport, but they were embarrassing, cringe-worthy, or ill-advised moments inside the sport.
All of them are moments that left some part of the sport uncomfortable or some part of its fans wishing they could look away.
Here's a look (in no particular order) at some of those moments that while embarrassing give the sport even more character as it works on its seventh decade.
