Revealing mistake: When Andy hits the pothole, - watch where the bike lands. It's almost immediately next to him. Andy pops up and says he's fine - the bike is nowhere near where it first landed.
Continuity mistake: In the opening credits, Andy tucks his pant leg in his sock. The next scene shows him riding his bike to work as the credits continue to roll - his pant leg is now out over the sock like normal. The next scene shows the sock back over the pant leg. (00:05:00)
Chosen answer: The words translated are "When you clean my room, I can't find anything. Where are you going in a hurry? The football game." Even if you can't understand a foreign language, the last word of the love song is recognizably "football".
