who was on the tee shirt worn by Duncan McKay in "Monarch of the Glen"?
Interesting question, thanks for asking! I poked around IMDB and Google Image Search on the off chance that Duncan had a 'signature' t-shirt that he always wore, but no luck, so I'll need a little help from you to find the answer. Do you know which episode you were watching when he wore this shirt? It's OK if you don't know the number or title, just tell me what you know about the plot of the episode. And it'll help if you have an impression of when in the episode it showed up, too - beginning, middle, end is fine.
Once we've got a bit more info to work with I'll try to find an answer for you!
