Top iPhone game for the bathroom

When it comes time to do your business it can be helpful to pass the time with a fun iPhone game but which is the best?! For me my top three are High Noon, Flight Control and Scramble with Friends. However of the three I'd have to go with the last as 'the best'.
High noon needs a pretty solid wifi connection to be effective and is still one of my top iPhone games of all time but it might be TOO addictive. You can easily play for 20-30 minutes at which time you'll have a really tough getting up from the toilet without some pretty intense pins and needles.
Flight Control doesn't need any internet connection at all except to check your rank which is helpful for bathrooms without 3G or wifi and is also a fantastic and addictive game but again, it might be a little TOO addictive.

Scramble with friends is the perfect bathroom game in my opinion because games only last for 2 minutes so you can play one game or as many as you may need for those trips that take a little longer but it doesn't have the "I HAVE TO PLAY MORE RIGHT NOW" factor of both high noon and flight control. I'm also just a huge fan of Boggle and finally having a way to play all my friends is awesome.
Words with friends could be categorized in the same discussion but it's just a little too boring for my taste. Other contenders would be any of the bazillion puzzle games out there including Angry Birds and Cut the Rope but we've all heard enough of those games anyway.
