Распечатайте все 12 стихов популярной праздничной песни.
В 12 стихах я подразумеваю повторение каждой строки, которая исполняется в песне, т.е.
Стих первый: В первый день Рождества моя настоящая любовь дала мне куропатка в грушевом дереве.
Второй стих Во второй день Рождества моя настоящая любовь дала мне два голубятника-черепахи и куропатка в грушевом дереве.
...
Стих N: На n-й день Рождества моя истинная любовь дала мне (Стих N-1 без первой строки) (строка добавлена в стихе N)

Edit:
Похоже, что вопрос прошел свой путь, и сайт навязывает мне принять ответ. Насколько я вижу, этот самый короткий. Я немного боюсь того, что сделает сайт, если я приму свой ответ - возможно, награжу меня значком нарцисса или мастурбатора.
Вы не можете принимать свои собственные ответы. Справедливо. Я оставлю его открытым. Спасибо всем, кто ответил.

Tell them it a feature
Say it not supported
Change the documentation
Blame it on the hardware
Find a way around it
Say they need an upgrade
Reinstall the software
Ask for a dump
Run with the debugger
Try to reproduce it
Ask them how they did it and
See if they can do it again. Не мой, но интересный...
