Best and worst proposal ideas ever

Let's face it, a pizza-delivery-turned-proposal is an amazing idea in theory - it ticks all the boxes (food: done, ring: done, trackie bs: done). It's just a shame that it does't make the most aesthetically pleasing sight in practice. Then there's the burger, the shower and the coffee cup - don't get us started on those. There are some creative ideas that do measure up, however. What do you think?
