Typical female: goes to bar, has drinks, goes to restroom, flushes toilet, toilet won’t flush, leaves bathroom.

Geek female: goes to bar, has drinks, goes to restroom, discovers toilet is apparently not flushing, takes lid off toilet tank, discovers that the reason it isn’t flushing is because the chain is too long and is preventing the flappy thing from closing by getting in the way, improvises fix on the spot, fixes toilet for future generations of helplessly confused bargoing females.

Mechanical inclination, /rawk/.
