It would be neat to write a little program to encode them as English sentences or something. – Nate Eldredge Sep 12 '14 at 06:07

Very true! Manually copying a 34 character address is no fun.
You have three major options:
- QR code. Print it out in advance.
- Create a FirstBits address.
- Bring your phone, and load a client that supports NFC.
By the way, if you enter someone's address wrong, the Bitcoins won't send - Bitcoin addresses have a checksum built in.

Concerning the checksum feature of addresses also see [What happens if I mistype the address when making a payment?](http://bitcoin.stackexchange.com/q/194/5406). – Murch Sep 12 '14 at 11:05

Yes, QR codes with an integrated camera capture are sufficiently convenient. Thank you – Jim Bob Dec 02 '14 at 05:51
