The episode "Road to Rupert"...they do a quick spoof of Spock's funeral scene from Star Trek II. Brian's kilted and on the pipes .

Also...I happened to read "The Mote in God's Eye" over the weekend, by Niven & Pournelle...awesome book, by the way. Many references to a planet called "New Scotland", various kilt references, and a few dialect jokes .
