I dare anyone on this thread to come up with an example that beats taht time CGP Grey tried to avoid jet lag when going to Vegas.
Vegas is easy though - especially on your own - everything's 24 hours and inside they seek to confuse you about the day/night cycle.
When I was 17, I spent two weeks in Florida, then returned to England for about 10 days (with nothing to do during those days) before going out to California. I tried to stay on US time and gradually move across from 5-hours out of sync with local time when landing in the UK to 8-hours out of sync when taking off again (so I'd go from being in-sync to in-sync when west of the Atlantic without any recalibration, gently shifting by about 20 minutes a day rather than jerk 5 hours one way then 8 hours the other) - that way I'm not only not jetlagged, but I'm also not tired the evening we arrive and so can go and eat dinner at 3am UK time/7pm CA time. Drove my mum mad, despite me explaining the plan repeatedly, and after a week she was actively and aggressively waking me 10am UK time (so 3-4am my time), then the next day 9am (3-4am my time - I'd moved back an hour due to insufficient sleep the day before), then the penultimate day 8am (ditto). My point, that she was having none of, that I was trying to moving to the point of going to sleep at 8am, so leaving the house at 8 for a midday flight just meant staying up late before having a 4 hour sleep on the plane from 4am-8am in the time zone I was going to, rather than her plan of dragging my clock across to the western-Atlantic so I need to wake up at what was basically 4am my time, having not had a decent night's sleep as it was the fourth night in a row that I'd been aggressively woken up way too early, and then have to spend the day awake on solar time (she made sure she was sat next to me on the plane and kept poking me awake), before falling asleep 6am UK time (OK, 2am my mid-Atlantic time isn't that bad, until you realise it was after 22 hours of awakeness and less than 4 hours sleep the days before) - I then got told off for nearly falling asleep at dinner, despite her having been nearly falling asleep repeatedly since about an hour after we landed (ie about midnight UK time).
Actually, planes tend to do this "what time it is where you are coming from is more important than where you are going" nonsense. My last plane journey was a red-eye from LAX to LHR that left LAX at about 9:30pm PDT. Dinner was served 10:30pm PDT / 6:30am BST and, while I'm no Florida retiree wanting dinner to be done by 5:30, this felt like we were moving times zones to the west, not the east! Making it night time at 11:30pm LA time for about 7 hours is acceptable until you realise that's 7:30am destination time that 'night' is starting. I eventually lost my fight against sleep about 3am PDT/11am BST - I'm a night owl as it is, but eating keeps me awake for quite a while afterwards, which got me to 2 easily, but the dull choice of films couldn't sustain me through the blackout - getting a totally unhelpful (I function, at least for a few hours, better on no sleep than not enough) 3 hours before they turned all the lights back on at 6:30am PDT/2:30pm BST to serve a light meal before landing at about 3:30pm BST. I was too tired to do a massive rant about how it made absolutely no sense to serve a big meal that late, and keep the plane under 'night' conditions until afternoon destination time. It would have been better to board, go to night about half an hour after take off, serving a breakfast 7 and a bit hours later, and then the big meal for a late lunch at the time we got our light meal. OK, still 6am-1pm nighttime, but that's better than what we had!
