This strip in the new Trade a Plane was really good! Are we going to see any more of the purple alien? All kinds of possibilities there:
*He lands, only Chuck sees him, they talk, alien leaves. Chuck tells everyone he met a space alien and, of course, nobody believes him. Have the alien show up from time to time with same result.
* Alien lands and he's the equivalent of Chuck from whatever planet he's from-- can't navigate, etc. He and Chuck thus form a natural bond.
*After alien and Chuck become friends, he comes back on Haloween. Chuck shows him off to prove he wasn't making the whole thing up, but everyone who sees the alien simply says something like "nice costume."
* Alien takes Chuck aboard his ship and hilarity ensues.
*Alien takes Chuck to his home planet for a visit.
I'm sure you guys can think of stuff along these lines. Of course, the alien would have to get a name. Maybe Kcuhc,.
