Sex positions "the crab" & "the wheelbarrow" (NSFW)

[RicherThanRichie]

ok so I stumbled upon this FHM clip of 28 sex positions *possible NSFW*
The crab comes on at 3:31 and the wheelarrow at 3:36 if you don't want to watch the whole thing

I nearly died laughing when I saw "the crab" and "wheelbarrow" Can anyone not in the circus get into these positions? I pretty sure I'd be willing to put up a hefty bounty to see an avg couple attempt one of these. Maybe this is some super advanced manuver I need to learn, maybe I'm inadiquate as a lover, but I can't see anyone actually pulling this off.

So my question for OOT do you think any of the sex acts can be successfully executed?
