{The {quick|fast|speedy} brown fox {jumped|leaped|hopped} {over|right over|over the top of}
the {lazy|sluggish|care-free|relaxing} dog.|{While|Although} just {taking|having}
a{| little| quick} {siesta|nap} the dog was {startled|shocked|surprised} by a {quick|fast|speedy}
{brown|dark brown|brownish} fox that {leaped|jumped} right {over|over the top of} him.}
