Back on May 21st, Victor Steinbok posted an example from a comment on Google+:
(1) Does anyone see what’s the tactic is?

(2a) … what’s the tactic?
(2b) … what the tactic is?

Searching for more examples of the form {“what’s the * is”} was pretty much hopeless, thanks to the flexibility of Google searches, but I did pull up a large number of examples of the form:

what’s the Expletive FormOfDO
