Sorry to hear about the gum... that really does SUCK!
The dumbest thing I have done? Well, I am sure there are many, and yes I divorced mine too... BBBUUUTTT... bike related:
When I was a kid, I had this bike with a banana seat. And, my friend and I would take turns "pumping" (one person rides on the seat while the other one pedals) each other. (Gosh that sound so *dirty* now!)
Anyways... so I was on the seat...and we had moved it as high as it would go (as you may recall, it was easy to adjust the seat to a new height).
So, my friend is pedaling... and I am riding.. and them... BAM! The seat post comes out of the tube, apparently we had put the seat post TOO HIGH and it wasn't "locked in".
The seat basically goes backwards (as those seats were also attached to the back wheel)... and I'm on the seat still... being drug through gravel in the street... because my silly friend didn't notice I wasn't up top anymore!
I skinned up my knees/legs... and when home whimpering... for sympathy.
My Mom took one look at me and DIED laughing! And was kind of laughing too... because it was pretty funny!
