Two old friends accidentally meet for the first time in months. Bob rushes up to Sam and gushes, "Oh, I'm so glad to see you, Sam! About 2 months ago, my life changed! You know how I was always hard of hearing? Welll.. I got new hearing aids! They cost me over $3000, but it makes such a difference!"

"That's great", Sam replies, "What kind are they?"

Bob glances at his watch... "Oh, about 11:15."
