Ok, i think the guy who plays stacy's boyfriend is hot so i hear a bunch of stuff about him and decide to search on his name(Shane Haboucha) which some ppl were saying was it. so i got this stuff: http://www.ussd.com/tourney_results.asp?tourneycode=2002.12.08.SoCal
it is some self defense class thing but his name appears Kata: Boys & Girls Brown Belt 2nd.
the other thing i found was http://www.simmonsandscott.com/ it was like some acting school, he is one of the pics on the right. it says he lives in Aneheim, california which goes with the self defense thing it says: Results from Southern California Tournament.
i found one more thing: http://www.cedvoices.com/search_results.php?mode=id&FileNameID=1533&id.x=19&id.y=15
if it goes to something not with shane go to LOS AngELES and to Haboucha, Shane it has a voice demo. i hope this helps.
