I'd like to have seen someone dig that underneath it without anyone noticing!
Hitler "What's that, it sounds like digging?"
EM (for it is He) " Nothing Adolf, have some more mind bending drugs"
Hitler "are you sure nothing is amiss?"
EM "Its stopped now"
Hitler "can you hear ticking?"
EM "I'm just nipping out for some milk"
