BUG: bool methods are wrong with DataFrame and Series (or at least wrong error)
```
from pandas import Series, DataFrame
s = Series([2, 3, 4, 5, 6, 7, 8, 9, 10])
d = DataFrame({'a': s})
s + d
d + s
print(d & s)
```

produces Traceback:

```

    mask = notnull(xrav) & notnull(yrav)
ValueError: operands could not be broadcast together with shapes (81) (9)
```

`s & d` currently raises `NotImplemented` instead. (because there's no `__rand__`)
