Lookups returning extra results

Lately, when I issue a "lookup" command, I get alot more back than I expected. For example, while attempting to get the contact info for a friend, I issued (via twitter) "lookup Bob Jones" (name changed to protect the innocent).

It successfully returned the contact info for "Bob Jones" as the first result, but then returned 10 additional results that were the all the @birthdays I had tagged it seemed. Any ideas?
 
silly I’m unsure
