"I do get a lot of mail. I get a lot of foreign mail because my mail gets mixed with Emilio Estevez"

This quote by Erik Estrada is most likely describing the reality that he and Emilio Estevez have similar appearing names. As a result, Erik Estrada obtains a great deal of mail that is intended for Emilio Estevez. This is particularly real for foreign mail, as the sender might not be familiar with the difference between the two names. This quote is likely suggested to be funny, as Erik Estrada is playing down the truth that he gets mail meant for someone else. It also acts as a reminder of the importance of double-checking names when sending mail, as it can quickly be sent to the incorrect individual. In general, this quote is a funny way of highlighting the confusion that can develop from having comparable sounding names.
