For the record, here is a picture of Chris Kratt.
This morning, Daniel was watching PBS - Sesame Street this time - and discovered that there is a character on that show named Chris. Daniel watched for a while and then came over to explain to me that, because the Chris-es have the same name, they have different colored shirts. The different colored shirts eliminate the confusion one might encounter in dealing with two individuals of the same name. It is, he explained, how we can tell them apart from each other.
