I had a week like that last winter. All of the following happened within about a week:

Fell on the ice on my way to work TWICE. (crazy ice/snow storm, I had to walk the last four blocks when the snow made it impossible to make it up the hill).
Tire got caught in a crack in my driveway and caused me to slip on some ice.
Tipped over after unclipping the wrong foot while carrying a frame on my shoulder.
Fell over trying to get off my bike while really drunk.

Last summer I had a flat tire week. Something like 9 flats in 7 days. Different bikes, different tubes, different kinds of flats.
