Phi Brain - definitely a fun show (it's like Yugioh-tier villains and heroes mixed in with typical anime SOL elements).
Ultimate Girls - This one will only be funny if you look passed the fact that it's so goddamn retarded. Honestly I had a blast watching this one.
Queen's Blade (Seasons 1+2) - Adding this one as a wildcard, because if you watch through the first season (which is terrible), you'll become engaged enough to care about the actual good plot in season 2. I mean, the whole show is pretty stupid and saturated with tasteless ecchi/nudity, but you'll be watching season 2 thinking "what the fuck this is actually getting good now".
