When you talk to him again, mention that you had a typo and make it into a joke. I've said some pretty shitty things in interviews and stuff.

Just last week this lady I interviewed with at Best Buy said "I want to see big things out of you in the sales department" and that only thing that I could think to say was "Oh, it will be big alright"....

I still got the job so it should be good with you too.
