I once bought a 4.5 kg Toblerone from Basel airport*. That was hefty enough to fill anyone's gap. To be honest, until this thread I never knew there was such a thing as a Toblerone tunnel or that it was supposedly desirable. My courting days are a long way behind me, but I was pretty happy if the object of my affection didn't apply for a restraining order. By the time you're inspecting her undercarriage for airworthiness, it's all a bit late.
It's the middle of the afternoon and I'm in an open plan office today, so I'm not moving my undercarriage to check if I've been justly blessed. Plus there's no Toblerone in the vending machine. I could try a Yorkie bar.
(*I swear there are people in our office who only ever eat when we bring stuff back from our travels, given their pirahna-like descent on any food item I lug back. The only stuff that stops them is the weird Japanese bean-paste sweets and pretty much anything I find in China.)
