My brother (who went to NASA camp one summer as a kid and later to study aerospace engineering) never enjoyed when I would tell him the moon landing was fake (so I continued to do it like an annoying older sibling).
I always like to think of a quote I got (and modified) from the XKCD webcomic: If NASA was willing to fake such a great accomplishment in manned missions to other worlds, then why haven’t we sent men to Mars or Jupiter?
