Andy already mentioned the monotony that is the Little Caesar's pizza lunches. I feel it is my duty then to warn you of the dangers of Papa John's pizza, which will be prominently featured at many a free lunch next year as well.
Beware Papa John's pizza. The corrosive nature of the pizza sauce will undoubtedly cause great harm not only to the mucous lining of your stomach, but also your poor gingiva. Eat more than two pieces and you will feel like you swallowed flaming razor blades that unleashed pure hydrochloric acid into your stomach upon digestion.
But those first two pieces are pretty good.
