Mine provides an excuse for swearing.

I was going to Apple Hollow (Franklin, QC) last summer and tried to re-route to get around a road block. It wanted me to go to Ottawa.

I went to Toronto for Christmas and it sent me to a ferry that's always closed in winter.

It comes in handy when I want to go somewhere that's not too far away, or I have enough sense to not follow its directions when it's being stupid.

John, what do you mean, "Oh Mary"? She tells people to do that all the time, pre-coffee, but I'm sure you remember that.

Mine works best when I just let it tell me where I am, and then use a map. I AM tempted to download the Sopranos voices. Easier to swear at. "Take a friggin' left up here, or ya end up swimmin' with the fishes, ya moron!" It's really easier to be mean to than some nutso lady who pronounces 'Cornwall' so it rhymes with 'porn PAL' (accent on the second syllable). "And take the 401 to Corn-WAL."
