[This shows a drill sample with various labels, in order from the top of the panel toward the bottom.]
[Against a short section of core:] Topsoil
[A more obviously granular shorter section with a diagonal transition:] Till
[A light and lightly-marked phase:] Granite bedrock
[Repeating the Topsoil appearance:] Bottomsoil
[A short/squat and possibly squeezed 'lump':] Roof of subway car
[A similar squeezed-out lump:] Floor of subway car
[A longer length of the 'granite' texture, within which...:] More granite
[Not quite half of a pipe-width, cut out as a gap perpendicular and not quite all the way across the core:] Municipal water main
[Slightly more grainy version of the 'granite':] Slightly different granite
[In a junction between 'granites', an squat, unidentifiable lump:] Piece of screaming spelunker's arm
[Within a longer granite layer, a short stretch of spiky/crystalline features:] Cool crystals with no resale value
[The same granite, an intrusion of mechanical-looking junk:] Mangled fragments of drillbit from previous attempt
[As per granite, but slightly more grainy:] Some boring intrusive rock that's basically granite but has a name like "diorite" or "andalite" that you always have to look up
[Dark, cobbly textured stone:] Netherrack
[Within a stretch of granite, a short, dark but otherwise unidentifiable lump:] Balrog wing
[At this point, there is a discontinuity indicating that an arbitrary length has been omitted. The sample then resumes:]
[Still 'granite': Granite
[Dark soil texture:] Topsoil
[Light, fine and sparse 'grains':] Cement
[Two very short cross-sections, each with contrasting wood-grain stripes:] Floorboards
[Two very short sections with a textile-base plus piles appearance:] Carpet
[A mish-mash of 'stuff', possibly including cloth, metal components, grainy wood and 'topped' at the lowst end by something equally puzzling at an angle:] Possesions of a confused and angry homeowner in the other hemisphere

Title text:If you drill at the right angle and time things perfectly, your core sample can include a section of a rival team's coring equipment.
