1 Ophelia: We need to help the war effort any way we can. Mercutio, do you know anything about cryptography?
2 Mercutio: I did four years of computer science.

4 Mercutio: That's a "yes".
4 Ophelia: Sorry, I thought that meant you spent 4 years playing computer games.
4 Mercutio: That too.

I did only one year of computer science at university before moving on to physical science. Several of my friends continued on to computer science degrees, so I often had occasion to visit them in the computer science department. And indeed it seemed that all they ever did in there was play games on the computers.

I guess I missed out on all the fun.
