And you, as the PM, typicaly expect them to ask a clarifying design question of some sort.  Here's the question I recevied Monday...

"Do you know where we could purchase sulfur or some other sort of fart smelling substance?"

Now, its a PM job responcibility to remove roadblocks for your team, but I just had to know how the answer to this question would effect our product development. 

"Its not, it's for a joke... but that might increase team moral we suppose."

At this point I didn't know whether to be scared or encouraging.  It turns out that Google can be as much a friend to PMs as it can be for developers.   But, for US citizens I think the Live.Com search results are better.
