Contrary to popular belief, suicide is not always your only option. There are several other things that you might also be able to do, depending on the nature of the predicament faced.
Any problem involving a girl can be solved if you Pee In Her Butt.
Many other problems can be solved if you Do a Barrel Roll.
However, if neither of these solutions seems viable, or if the root cause of the problem is that you phail at life, then suicide is, in fact, your only option.
