20 min. I caught him when he was smiling at something the professor said (our Professor is pretty funny and tells us random, offtopic stories during class).
20 min. each.
1.5 hours w/ help in the beginning from the professor . You can tell he helped me because the head is not ridiculously small like usual. Makes me realize that I *REALLY* need to watch my head sizes...I tend to make them a little bit too small for some odd reason.
