The Problem: Your Mother is far too cheap and cruel to buy you pudding in a tube. This is a heartbreaking disappointment as EVERYTHING tastes better in a tube.
The Solution: Dig in the trash and find a four-day old empty fruit snack package. Then carefully spoon the contents of a pudding cup into the package. Voila! Pudding in a tube! As an added bonus, the cheap and cruel Mother will get to spend twenty minutes cleaning up after your moment of creative genius. Just don't get the idea that you were being all sneaky with this endeavor. The cheap and cruel Mother most likely knew everything that was going on, but was curious to see how far you planned to take this little project. The cheap and cruel Mother thinks that was a heck of a lot of effort just to get to eat pudding out of a tube. But cute.
