I honestly don't know how you kept a straight face during this meeting. This reminds me of the time that I was in one of my graduate school discussion seminars and we were on the subject of some rape incident in the 1960s. There was an older gentleman in the room who was talking very seriously about it and said something along the lines of "I could ask my old friends of the time how they had felt about it, use them as primary sources, but I can't because they're all dead now." For some reason this struck me as particularly hilarious and I let out a completely inappropriate chortle. I attempted to disguise it as a bad cough and left the room to "get some water." Laughing about rape and death probably isn't a good idea!
