Formation of Sentences

I am in the mid of a class and I cant stop laughing at what the instructor said...
He wanted to convey "He ll begin teaching the concepts from the scratch."
He said "From the scratch, I am starting"
I heard it as "From the start, I am scratching" ;)

Funny, the language called English and the way some of us use it.... Funnier, what the mighty mind can do to sentences ;)
