We've seen plenty of novelty cufflinks
in the past, but these ones -- well, they're actually kind of useful, in addition to being cool and weird. These ones are a pair of 4GB USB flash drives which are disguised to look like... well, cufflinks. They come in gunmetal, gold and silver finishes, and they're engravable to boot. They're not super cheap at $195 a pair, but if your dad's the kind of guy who needs to have a lot of top secret documents on him at all times, they might not make a bad Father's Day gift.
