6. Something Ridiculous
Okay, time for some comic relief. Obviously none of us want the Doctor to regenerate at all, but a favorite headcanon among all Whovians is that Eleven, being so childish at times, should regenerate because he stepped on a lego, or something that causes humans to spew profanities. Hitting your funny bone, stubbing your toe, banging your head against someone elses, anything that causes humans to go #!*!&23!*@&&#;!!!!! It would be nice to have a regeneration that wouldnt be so upsetting (beyond how upsetting any regeneration is), but of course, the Doctor only regenerates when he dies. We could argue that something happens, such as falling from a really high distance (Jodrell Bank, anyone?), and then something small causes his body to finally 'collapse.' The impact of something so small causing a regeneration means we could almost laugh at the process, which is something we've never done before. However, it is Moffat and we all know that the regeneration is going to be absolutely horrible. So 0/10 for this one happening, no matter how funny it is to imagine.
