There's some obvious and easy ones, like multiplying φ times e^i before raising it all to the zeroth power, but I propose the following:

Replace the 1 exponent on the right side with (φ²-φ).

I don't have enough information, in particular, how many trick-or-treaters you typically have. I'm going to say 8%.

Ranking member of the House Homeland Security Committee Bennie G. Thompson said in a statement “Mobile Fortify is a dangerous tool in the hands of ICE, and it puts American citizens at risk of detention and even deportation.” He also said “ICE officials have told us that an apparent biometric match by Mobile Fortify is a ‘definitive’ determination of a person’s status and that an ICE officer may ignore evidence of American citizenship—including a birth certificate—if the app says the person is an alien. ICE using a mobile biometrics app in ways its developers at CBP never intended or tested is a frightening, repugnant, and unconstitutional attack on Americans’ rights and freedoms.”

New incredible detail here: ICE says a match in its facial recognition app Mobile Fortify is a "definitive" determination of a person's status, and that this overrides birth certificates. This is an app ICE is using in the field to scan people

It looks more legit than any of the other obviously fake AI stuff I've seen, but that's not a definitive answer.

Melded* not moved, my bad, forgot the polymorph rules, and was trying to answer fast. I do like the ticking time bomb interpretation several others have put forward, and stand by my assessment that the polymorphed individual is likely not living for long.

Which is presumably why the Treasury Department told its employees not to share photos. They can't have people seeing perfect metaphors for the state of things, or the truth about the White House renovations.

But also, if you want to do explosions, you do you! Odds are the polymorphed individual is dead in any case.

I think, rules as written, it rips a hole in the fabric of space-time. (Destroys both items and opens a portal to the astral plane).
If you're looking to rule otherwise, you could always argue that when they're polymorphed the portable hole got moved somewhere else, like a pocket dimension.

A map showing the estimated travel time from Oceanside to San Clemente as 2 hours and 17 minutes when it would normally be about 30 minutes.  The map also shows that the five freeway along Camp Pendleton is shut down due to a Trump ordered military demonstration involving live fire from a naval ship across the freeway into the marine base.

Someone posted this on Reddit. Sort of an extreme example but still, even using the 15 for some of the shorter trips winds up more than quadrupling travel time. Even something like Carlsbad to Irvine would see its time more than doubled using the 15.

Many is a bit of an overstatement, if you want to get from San Diego to LA and the five is closed the only other option is the 15 further inland. Anything else is either surface streets or all the way in the desert, adding several hours travel.

I didn't realize it was that easy to ruin their day, That's not typically my motivation for blocking, though I suppose I could make an exception. Since I don't do block lists, I can personally give them one more thing to die mad about.

A large crowd of people stretches down the street.  They're holding anti-Trump protest signs and waving American flags. Cars are honking and waving as they drive past.

I didn't make it to the big event downtown, but one of several local satellite protests still pulled at least a thousand people spread across a couple streets. #NoKings

Probably a little bit at least, but it also means there's plenty of smarts to work with there. I'm already having to keep an eye on the sneaky tendencies of my 8-year-old, so I'm sure I have stuff like this to look forward to in 2 years.
