This wouldn't happen anymore, because they've changed the logic about default crews, but once, back in the 0.20 to 0.22 era, I made an Apollo-style Mun Lander. When I got out to the Mun, that was when I found out that in addition to my 3 Kerbals in the command module, I had also brought along 2 kerbals in the lander can.
