Stuttering s..s..sucks! - Thats Embarrassing!!

I was in 3rd grade, and i had to read out loud a paragraph from a story. I came to the part that said "Mr Rabbit said, 'oh my, but Mrs Squirrel,that would not be nice'". I got stuck on "oh my but", I kept repeating "oh my but oh my but", and the whole class was dying laughing!! I got sent to the office, i really didnt mean to, I was so humiliated!
