We have just hit a major problem which may seriously impact on the successful delivery of the lecture in rhyme. It is called "Babylon 5 Series 1 on DVD". Several courses of action are open to me:
Watch the entire series (22 episodes) and then write the lecture a week after I give it (only possible with Time Travel and Stasis technology presently unavailable from Dixons)
Don't watch the series, but write some poetry instead (only possible with willpower presently unavailable to the author - all available power presently directed at giving up chocolate for lent...)
Institute some form of positive feedback/reward system - perhaps something like watching one episode per completed verse (currently finding favour with higher brain functions - although the temporal calculation division have pointed out flaws in this plan).
Only time will tell
