bored out of (one's) mind

Extremely bored to the point of distraction, frustration, or irritation. I was bored out of my mind listening to that lecture this afternoon. We thought a week in a secluded cabin with no TV or Internet would make for some great family bonding, but we all became bored out of our minds after a couple of days. A: "Sorry for dozing off, but I just get bored out of my mind watching these old-timey movies." B: "Fine, go back to sleep then."
