One day after the second inauguration, President Obama, first lady Michelle Obama and first dog Bo surprised tourists at the White House on Tuesday afternoon with an in-person appearance.

The first lady gave Twitter users a heads-up of the surprise visit in a tweet from her account on the micro-blogging service:

Shhhh! Barack, Bo & I are about to surprise folks on @whitehouse tours! I love doing this. Watch here: wh.gov/live –mo
