Batman and Scooby-Doo are teaming up for the first time since the early 1970s, in a bizarre episode of Batman: The Brave and the Bold airing April 1. And here's our first glimpse!

The crossover airs as part of a special episode called "Batman's Strangest Cases," in which the all-powerful Bat-Mite (Paul Reubens) takes us through some weird alternate realities. Including the Scooby-Doo crossover, which is done in the style of early 1970s Hanna-Barbera animation. And an old Mad Magazine spoof from the 1960s. This is the episode the show's producers told us about ages ago.

But will they include the thing where Batman's pants randomly disappear whenever he talks about the Rubber Factory? [via TV Guide]
