Helen Keller Alarm Clock

When someone (usually early in the morning) lets lose a silent but deadly fart. There after the persons partner who is then sleeping soundly in the bed with them, is awoken silently by the horrendous smell and looks up only to find the offender staring blankly back at them.

I was in a deep peaceful sleep when suddenly I was jolted out of my sleep by a terrible odor. I looked up and found that my partner had just given me a Helen Keller Alarm Clock.
