Correlation between LOD and SSN???????

WUWT posts that there is a correlation between length of day and Sun Spot Number

My response:

Not sure were all the data in the header comes from but this is the plot I get for LOD and SSN

There seems to be no correlation worthy of note.

This is their take on it:
