I am a strategic liar. I build up credibility for The Big Lie.
Any lies I tell are generally on the social level, like saying "Hi" when I mean "Go to hell, you worthless prick." Stuff that's expected, you know. I try to own up specifically in cases where most people would lie, just to build up the impression that I'm honest. In most cases it just isn't a big deal if I'm five minutes late, so why bother?
Then, when I need it, I have The Big Lie. My best use of it so far was in my senior year in college, when I set up a professor who I'd had for several A's previously. Half of our final grade was a huge pain in the ass paper, and I just didn't get it done before it was due. I ran into the professor somewhere on campus a few hours before the deadline, asked him when he'd be in the office, etc. I dropped by his office later and engaged in conversation but didn't actually turn anything in. I went home for the weekend, finished the paper by Monday, back-dated the file just in case, and went about life as normal.
After a few days the professor saw me in the hall and asked if I'd turned in a paper. I told him I had, and referenced the conversation we'd had in his office. He said he'd look for it again. Friday, a week after the due date, he said he couldn't find it and asked for a new copy, which I provided later that day. All in all, I got a week extra to work on it (even though it only needed a few more days), and an A, because I'd set him up to believe I was honest and acted consistently.
Whether he actually believed me or not was immaterial, because he had no reason to suspect me (and also I hid a duplicate copy of my paper in his office, later).
I do have a phobia related to falling, though escalators aren't a problem. Looking at that horror bridge at the Grand Canyon made my palms sweat. Yerg.
