In the season 5 episode It's My Party, Tia is showing a picture of Tamera and herself at what she claims to be their Sweet Sixteen birthday party last year, when clearly it wasn't. The photograph did take place on the twins' birthday, but not their sixteenth. It's actually from the season 1 episode The Birthday, where Ray and Lisa take the girls and their then friend Sarah to Chigago for their fourteenth birthday. How could they have been sixteen in that picture, when the episode took place in the first season? Also, the girls' friend Sarah was absent after season 2, and the girls are depicted with curls, but all through out season 4 they wore their hair straight.
