LOL, I went to the orthopedic clinic yesterday LOL

I told the doctor, "Since I'm running in a marathon..." blah blah blah,
and just as I was about to leave after my checkup, the doctor was like, "LOL"
"What was your time? It was raining, too, wasn't it? ㅜㅜ"
So I said, "I finished in 4 hours and 19 minutes,"
and the doctor went, "Huuuuh... [gasp] That is truly amazing" LOLOLOLOLOLOL
