Drinker

飲酒運転のことを　DWI、"driving while intoxicated"　と言うことを前に書きましたが、飲酒運転の面白いジョーク（実話？）を紹介します。

When the driver in front of my police car began weaving in and out of his lane, I quickly hit the sirens and pulled him over. As I approached his window, I was hit with the stench of alcohol.

“Sir,” I said, “can you tell me when you started drinking and how much you’ve had?”

“Well, Officer, I can’t tell you how much I’ve had,” he slurred. “But I started drinking in 1967.”

この人はきっとこれまでに何百杯、いや何千杯、もしかして、一日に一杯飲むとしたら、もしかしなくても１万杯は超すか、飲んだのでしょうね。

chuckle vs. giggle

RD(Asian Issue) September issueのHumourに関する特集記事の中に Chucklers are kind but introspective and gigglers are sexual and flirtatious. と言う記述がありました。
そこでchuckleとgiggleの違いについて英英辞書に当たってみました。

Dictionary.comによると、

Chuckle -verb (used without object)
1. to laugh softly or amusedly, usually with satisfaction: They chuckled at the child's efforts to walk.
2. to laugh to oneself: to chuckle while reading.

Giggle -verb (used without object)
to laugh in a silly, often high-pitched way, esp. with short, repeated gasps and titters, as from juvenile or ill-concealed amusement or nervous embarrassment.

確かに微妙な違いがあるようで、Chuckle は子供っぽく、Giggle の方は微妙な影を含んだ笑いのようですが、これを日本語で区別するとどうなるのでしょうか？
どちらも、「クスクス笑い」、「含み笑い」になってしまうと違いが分かりませんね。
