Why my boss makes fun of me in front of everyone.?

My boss thinks I'm flakey, or at least one would infer that by his comments. Every day I stress wondering when and how many times he'll rib me in front of co-workers. For example, today I turned something in, but it wasn't due until tomorrow. When I said "sorry, I guess I'm off 1 day", he loudly said, "You've been "off" for a L-O-N-G TIME!" Everyone laughed as usual. This may sound silly but I cried for 30 minutes (no one knew). Unless absolutely necessary, I no longer speak for fear that anything coming out of my mouth will be made fun of. Ironically, I get great evaluations every year, as well as a raise. He tells me how he values my work, etc.... I find myself getting very resentful of him though, and have visions of telling him off. I used to joke back with him when he'd make fun of me, but now I don't even respond. It doesn't matter though, because everyone else hears it. I keep thinking had I not joked earlier in the working relationship, none of this would be happening. Am I being too sensitive? I love my job and salary, except for him. One co-worker thinks he doesn't realize he's actually hurting my feelings. She said she bets he doesn't have a clue and to not worry about it. I guess what I'm asking is should I continue to quit acknowledging his "jokes" and bite the bullet? Granted, the comments may not seem that hateful, but it is constant.
