sort of? i mean it wasn't anything serious, but truly embarassing. it happened when i was 14 on some additional math classes which i only signed up for because my friends convinced me to. the classes were boring so instead of paying attention i would listen to music or play games all the time. i thought the teacher wouldn't notice that and well she didn't until one day where i forgot to turn down the brightness of my screen while i was watching a music video and she was walking through the classroom. she saw what was on my screen and assumed it was something inappropriate (in the part of the video which she saw the vocalist was sitting in a chair with an unbuttoned shirt where you could see a part of her bra but it was really nothing that bad) so she made me stand next to a wall with painting of some mathematician for the rest of the lesson and said something like "so this is what children do now?! i will pretend i didn't see that, at home you can watch whatever you want but i hope you know that your parents wouldn't be proud of this"
