... that's he Russian army chipping away a tunnel under your building.
And who do you think PUT those leaves on the line? Al Qaeda that's whom!
And you know when Fox is on the TV and you want to turn over, but the TV remote has gone, but you put it down only a minute ago, and you're sure you know where it was, so who could have taken it? Mossad!

Lots of Spooks plot material there:
Picture the scene, two turban wearing unshaven faces are hiding in the bushes next to the railway line. The 12:13 from Chipping Norton, rushes by... "neeeeeeeeee niiiiiiiiiiiiiiiii" goes the train.
One terrorists mutters 'durka durka' to himself then places some green leaves on the metal rail. The other pours water on the leaves to make them wetter. "NO Mustafa, we cannot be so cruel as to put WET leaves on the line", "YES Osama we must make the infidels pay! Durka Durka Durka".
In an concrete office block in the city, a lonely old woman name Djacki tries to convince her boss of the threat.
Djacki: "There's a real and dangerous threat from leaves on the line, we have to act now! I am the only one who understands how dangerous this threat is!"
Boss: "Don't be silly Djacki, you're letting your imagination get the better of you! Nobody would be so evil as to put leaves on the line!"
Djacki: "They're so evil, they have leaves already pre-wetted in safe-houses around the country!"
Boss: "Wet? Good god no! Diabolical evil!"
Djacki: "There are some risks I'm not prepared to take. We need to send a strong message to these foliage-istas that we will not be terrorised by their tarrying of mass transport!"
Boss: "I am swayed by the alliteration in your argument Djacki, do what you must."
