He's European - they all seem that way whether they are or not.
Prince Albert is a brand of pipe tobacco sold by John Middleton, Inc. The brand gained widespread recognition, perhaps infamously, due to the classic prank call, where the caller asks if the store has "Prince Albert in a can" and when the unsuspecting clerk responds "yes", the caller follows up with "You'd better let him out (before he suffocates)!"
Despite (or perhaps, due to) this negative publicity, Prince Albert is one of the more popular independent brands of tobacco in the USA. More recently, it has also become available in the form of pipe-tobacco cigars.
Though there have been several Princes Albert in the monarchies of Europe, Prince Albert tobacco is not named for the most well known Prince Albert of Saxe-Coburg and Gotha who was husband and Prince Consort to Queen Victoria. Albert and Victoria's eldest son was also known as Prince Albert before he took the throne as Edward VII. The brand of tobacco was introduced after the Prince Consort's death, and the image on the can shows a man with full beard, which the Prince Consort did not wear. Also, wording on the package was changed somewhat once Prince Albert had become King Edward VII.
There are also variants of the joke involving King Edward brand cigars (named for Edward VII) and Martha White brand flour. The prank caller inquires if the store has "King Edward in a box" or "Martha White in a bag."
