Speaking as a former Washington intern (although not a page) it is extremely unlikely that any "prank" like this could happen. Granted, I worked for the Democrats. Maybe the Republicans IM underage boys and ask if they are horny for a funny ha ha, but I think the closest thing to a prank we ever had in our office was we sent Hillary Clinton's interns running after photocopies of a pointless letter. That, or when my boss brought a Nixon mask to work.

Political offices are still offices. There is a level of professionalism that must be maintained.
