Answer:
he stood back to back in the bigbrother house next to some guy called maggot or someone similar to that name . maggot said before he was just over 6,5 so say 6,5.5 and Dennis looked a good inch taller so i would say Dennis is 6,6.5 tall bare foot , more than likely got measured in his boots in the nba which gave him 6.7 .5 with them on , so the nba rounded his height of to 6,8 .
