Frank Caliendo is an early riser.

For example, the comedian and impressionist extraordinaire was all set for a phone interview from his home in Tempe, Ariz., never mind that it was 7 in the morning. In fact, he said he’d been up since 4 a.m. and had already done a little swimming. That doesn’t sound like the life of a big-time comedian with frequent travel dates, television appearances and late nights.
