The US Secret Service is on top alert after a series of white lines mysteriously appeared in Washington DC, apparently leading to the White House.

Alien expert Erik Von Hamburger told FNN:

These white lines have been discovered all over the world but are particularly prevalent in the jungles of Colombia.

That they have now reached the White House shows that aliens are still active on earth and continue to leave clues as to their existence.

If you see these lines, please do not lick or snort them.

The last person who did that seems to have lost his mind and now claims that Putin is fighting a war in Iraq.

I have sent a robot to Washington to investigate. If you see him make sure you greet him with:

Gort, Klaatu barada nikto

That way you won't be incinerated.
