    BUTYNIN = butting in
    Picture an OX sitting at the bottom of a water slide, completely BUTTING IN and blocking it. Water piles up behind it, exactly like what oxybutynin does to the bladder. The ox has a big 3 on its side because OXY has 3 letters. A confused med student stares and mutters "Ummm... M?" yes, the M3 receptor. M3 blocker.
