The Dragon Song, if you're willing to venture into the realm of sexual euphemism & double entendre. It's TTTO "The Irish Washerwoman."
Less simple, but still silly & double-entendre-ey is Tom's "Superman Sex-Life Blues."
180˚ from that is "Monsters In the Night," from the point of view of a small child.
These are all oldies but goodies that I almost launched my musical career as a singer-songwriter of filk in the folk community, (but graduate school sucked that all away). They went over well for mundane audiences. I have more such titles, but while they're still silly and appealing, they're less easy.
