PL100, can I call this? vs. maniac/moron

[neverforgetlol]

Now against a decent player this is an easy fold. But vs. an aggressive player (who can have almost anything, i.e. this person), can i call here? I'm getting at least 2:1, and am 54% vs. a random hand. The other guy, cros, is a moron as well and can have a wide range.
