Is seriously just bs-ing his through being a wizard.

Tries casting a spell and looks at the bard, "I saw a cleric do this once."

Weaving his hands through the air and shouting, "HEAR ME, O GREAT TORM! Torm is a god, right YES, TORM! GOD OF.... Healing? War? Law? UH... FORGET ABOUT THAT, GREAT TORM, HEAL MY ALLIES!"

Then sitting there, crossing his fingers, "please let that work, please let that work" and when it does he celebrates a little bit, then regains composure, looks at the bard, "told you I knew what I was doing."

What do you all think? What kinds of spells should he have? Any problems with it?

Edit: I thought of a few more hilarious situations.

Casting fireball and having a huge blast of electricity shoot out, he sits there a moment... "OH! It's 'by the flames of the nine hells!"

Uses a bit too much power and lightning bolts a mile away, "wait.... How did I even do that?"

Hits something with cone of cold, but it's an illusion (Int save). "Oh... Crap! Why can't I ever get that hand motion right?"
