Another report from Jeff Shaumeyer on Facebook:
“If you happenly want to convert …”. I don’t think I’ve ever heard “happenly” before, but it seems potentially quite useful.
A respectable number of ghits for happenly, conveying ‘happen(s) to, (as) it happens’, etc. — an adverbialization of the verb happen. (There are also some hits which seem to be mistakes for happily, but I’m disregarding them here.) Some examples:

Seriously ladies, no one likes a girl with straight bangs. You look gross. No one wants to look at a girl who it so happenly appears that their hair stylist used a ruler to cut your bangs in a perfect line. Let me put it this way from Napoleon Dynamite and Borat: I like yo bangs. NOT! (link)

Happenly, most of the cites seem to come from non-native speakers of English (many of them probably Chinese speakers), so the innovation is likely to be mostly a foreignism. The derivational formation (V + -ly = Adv) isn’t a productive one in English, but of course playful morphology (where the usual patterns are deliberately stretched) could be at work in examples like the second one above.
