Cannot open your terminal '/dev/pts/0'

I encounter this often, I am logged in as a colleague on a server by jumping from my user and using sudo su <username>. They use a lot of screens to manage processes and sometimes I need to access it. However a simple screen -x <id> does not work:

Cannot open your terminal '/dev/pts/0' - please check.

Ooh you! Simple solution:

script /dev/null
