From my good friend Tom Whipple over at The Times:

Google directions to San Francisco. Very clear, detailed and diligent and as you would always expect with Google.

Except step 37.

1. Head south on A3212 toward Great College St 0.4mi 1 min
2. At Horseferry Rd, take the 1st exit onto A3203 0.2mi
...
...
33. Turn right at Quai Colbert 358 ft
34. Turn right to merge onto Rue Marceau 0.2 mi
35. Take the ramp onto Quai Frissard 0.6 mi 2 mins
36. At the roundabout, take the 4th exit onto E05 0.6 mi 2 mins
37. Swim across the Atlantic Ocean 3,462 mi 29 days 0 hours
38. Turn left at Long Wharf 0.1 mi
39. Continue on State St 427 ft

I'm flattered by the pace they think I'd hit.
