With apologies for the (only somewhat) click-bait title, in an answer to another question (see [this answer](https://law.stackexchange.com/a/84028/44033)) the statement 
>Typically the only thing a legal entity that is not a natural person cannot do is sign a marriage contract.

was made. Some commenters disputed this, asking e.g. "can a business become a (natural) child's legal guardian, can a business have power of attorney over a (natural) person, etc.?". This got me curious:

**Can a legal entity adopt a child?**

Or does one, perhaps, need two corporations to do this? Of course, the answer to the above may be a simple "no" for trivial reasons, but my question is really closer to asking the looser question:

**What is the most ridiculous thing a legal entity can do that one would only expect a natural person to be able to do?**

I'm happy with any interpretation of "ridiculous", here. As pertains to jurisdiction, I've put the tag "united-states" for starters, but I am interested in other jurisdictions too, e.g. the UK (one commenter mentioned that corporations frequently vote in elections in the City of London).
