well I don't know about embarrassing...but I can tell you one of my most humiliating moments (or do they mean practically the same thing)...this is a little lengthy so bare with me.
One night I was a little on the tipsy side and driving (I know stupid on my part...learned my lesson this night)...well I decided all of a sudden to turn down this street to visit a friend of mine...now at the corner of the two streets used to be a gas station and one of the concrete blocks still sit there (big concrete block)...low and behind...what do I do...dumba$$ me runs my vehicle right over top of the thing and there I sit teetering up and down...every time my tires would hit the ground they would squall where I was pushing on the gas trying to get off the thing...and there across the road from me people starting coming out of the small town bar to stare... needless to say I sobered up real quick!! Finally a carload of guys stopped to ask if I needed help...I felt like saying "No I'm sitting here on this concrete block for my health!"

...but I didn't I know they were only trying to be nice

...the guys got me off the block and well I wished I could say my dumbness ended there but it didn't...I preceded to drive my vehicle around after the guys warned me not to because it appeared that I had busted out my oil pan...transmission lines and bent my frame...but would I listen...nnnooooo not the invincible one here...well of course the car died...would not move...would not even turn over and here I was in the middle of nowhere...freezing cold outside and no traffic...I ended up falling asleep in my despair...when I woke up I seen someone coming and of course I flashed my lights...he stopped and offered to help...the only thing I knew was to go into town and call mom and dad...so he gave me a ride (I know another stupid thing to do...remember I said this was humiliating)...the only thing that dang guy wanted to know is if I was gettin' the "buzz" on

...the guy took me to a pay phone and offered to wait around for me, I just thanked him and sent him on his way...I called mom and could hear dad in the background "well if she can't drive no better than that...she don't need a license!!"

...while waiting on mom another carload of guys stopped by to my rescue...by this time I'd had enough...practically snapped their heads off at the shoulder...they left quickly!
This happened about 8 years ago and my friends still poke fun at me about it
