In the first case the short story Jupiter Five, my favourite by sir A. C. Clarke, partly due to the excellent and slightly unusual Czech translation.
Profesor Forster měl tak drobnou postavu, že pro něho museli vyrobit speciální kosmoskafandr. (Profesor Forster's stature was so small they had to make a special spacesuit for him.)
In the second case this was the (perhaps more widely known) novel Harry Potter and the Philosopher's stone:
Mr. and Mrs. Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much.
When a story starts with a sentence like this, you just know you're in for a treat :-)
