Random rantings on Text/command line inputs...

While I was doing some research on Text-Based games such as King's Quest, I often wonder how much do these interfaces cater for funny inputs by the user?

For you programmers out there, you know how we like to compile using the "Make" command?
Well I was doing some C++ stuff the other day, and I wonder how smart is the Compiler in natural language processing, and I came up with an interesting error message when I try to "Make Love" (LOL)

Here's a snap shot!

The computer as expected, not only that it doesn't know how to Make Love, it doesn't acknowledge the existence of such concept!

LOL..
