As she pulls out one of those translucent brown thing from between two molars

And that's why I floss 3 times per day

Isn't the awkward moment what she pulls out? Without the title, there's nothing awkward about this.

I had popcorn the afternoon before a dental appointment one time and forgot As the hygienist is doing the regular pre-dentist cleaning she says in her heavily southern accent what I hear as "Oh, I found a hole." My mind freaks out, and around the fingers and tools I mange a "What?!" "Found a hole. You had popcorn earlier?" Never have I ever eaten popcorn the same week as a dental visit ever since.
