(Slightly) silly but working characters

So I was looking at the Escalation Mag 2 Warlock today and thought that it would make a really nice multiclass combo with the Dark Pacts Warlock, but then you‘re playing a multiclass Warlock / Warlock.

(Aside from the naming silliness, it works really well, because you get at-will spells and an encounter power from one side, and daily spells and more „let‘s make a pact“ class features from the other...)

What‘s your „slightly silly but working“ character idea?
