This is coupling
Do you want to see an example of what coupling is?. Take a look at this post at The Daily WTF.
This is something we all have done at least once, and if we haven't done it, it is something we will do in the future. There are many situations when these solutions are the faster and easier, but what happens with the developer that will have to maintain ( and maybe improve ) that code?
That is what design pattern and best practices are for.
