Mr Pear

Ok, this may be a silly question, so at least try to be nice Anyways, I kinda crashed two kerbals at mun, and they're stuck there.. (because the rocket tipped over). How am I supposed to rescue them!? I can't rescue them with a command pod, cuz they're all occupied by Jeb and his mates. Note. I do not want to terminate them, I want to rescue them. So, is there any way I can get them back. Like with a fuselage (aren't they full of fuel) or a extra set seats? Thanks for any replies I may get
