2 come to mind, first was just last year, playing on a local course, had hit a good drive to about 100yds or so. Pitching wedge to within about 2 inches of the cup, tap in for birdie.

Second was probly 4-6 years ago, maybe longer (memory stinks). Playing with some buddies who are usually substantially longer than myself off the tee. They both hit their normal 275+ drives and I step up, did nothing different to my knowledge, and literally almost drove a par 4 off the tee. The only logical explanation Ive ever come up with is the ball landed on a rock or something and just took a huge leap forwards and rolled to about 15yds of the green. (I still bogeyed the hole )
