Walked on ice, that's a funny one. I lived every winter all winter as a kid on ice. Non-stop hockey on the ponds.
Seems normal to me, but everyone is shocked if I talk about it. I'll have people talk to me about riding a bicycle and I'm like, "yeah, we just finished riding around Lake Ontario." Takes them a moment to realize we didn't ride around the area, we left Buffalo, circumnavigated the lake through Canada, back to NY, and back to Buffalo for 600 miles. People are shocked because to them a bike ride is 10 miles out on the river trail or such.
