...although being a novice breadmaker myself there's not much difference that I've found in the quality of the fermentation from using beer instead of water for a dough, you usually prime your yeast with some sugar or it eats the fermentables in the flour if you're doing sourdough or not using the sugar, sugar just gives the yeast a kick in the right direction so you've got tighter controls on how long your rise will take.
As far as sugar is concerned, breads with sugar additions are usually enriched breads, and derive the flavour more from the enrichments (butter, milk, sugar, egg) than from the wheat. So the beer would be for taste and caramelisation, not necessarily for better fermentation.
With bread, generally, a faster fermentation does not result in better bread. Because dough is already such a nutrient-rich environment, nothing is really needed to "kick-start" the yeast; in fact, some would argue that the flavour development of the dough suffers when you intentionally quicken/enhance the rise. But, that's a whole can of worms, anyways.
Besides the inherent flaws with the facts, its still an amusing comic
