I got a Floatzel in a random trade, so I will wonder trade to get a chain of 50 pokemon just to see what I get. All competitively viable ones (ones that are obviously breeding rejects) are bolded.
50 trades later: Floatzel->Rotom->Furfrou named "Dogy"->Honedge->Weedle->Skorupi->Scyther->Larvitar (3IV w/ egg moves)->Nidoran (female) (3 IV, HA)->Numel (3 IV)->Mawile->Skrelp (4IV, Modest)->Floatzel (not the same one)->Geodude nicknamed "SH*T" (don't know how it got past censors, it said the actual word)->Shieldon->Hoothoot->Chingling->Fletchling (3 IV, Adamant)->Ducklett->Eevee->Lapras->Miltank->Bunnelby->Fletchling->Spinda->Weepinbell named "Sprout"->Ferroseed->Luvdisc->Pidgey->Gothorita->Ralts (5 IV w/ egg moves, made to be a Gallade but it was female)->Makuhita named "Colour"->Bulbasaur (2 IV w/ Leaf Storm)->Houndour (3 IV)->Floette->Sneasel->Flabebe->Dedenne->Zigzagoon->Chikorita->Pancham->Togepi->Fletchling->Shelmet->Gible->Sceptile (5 IVs, Timid, kept it :D)
And that is how my chain ended at not quite 50, but close enough. Wonder Trade can give you some stuff that you just have to wonder what the story behind it is.
