Katie Hannaford, 36, ended up a little more than just embarrassed after her tumble left her flashing teachers, parents, and students all at once.
Her eight-year-old daughter had begged her to join the race, and while Katie agreed to make her happy, her daughter might be rethinking that choice now.
Everything seems to go fine at first, but just seconds after the race begins, Katie loses her balance and goes flying headfirst into the grass, her legs flipping into the air.
To make things even worse, her light blue dress flips right over her head, giving the crowd a full view of her underwear.
Luckily, Katie, who owns a home goods business, was able to laugh it off. Although she was pretty mortified at first, she now says the whole thing is just hilarious.
“I’m not sporty at all, but [my daughter] kept begging me,” she said. “In the end I agreed to the race – I knew I’d come last.”
“I was humiliated at the time, but it is what it is! I flashed my underwear which is obviously embarrassing but you just have to own it.”
“Looking back, it’s hilarious – definitely the funniest thing I’ve ever done in my life!”
“If you can’t laugh at yourself then what’s life about ay! Sorry kiddo’s and anyone else watching!”
It didn’t take long for the video to blow up online, with hundreds of people jumping in to comment on the hilarious moment.
Someone else added: “I’m laughing more this morning than I was last night.”
You can always count on the internet for some good old-fashioned laughs!
