動畫《奇天烈大百科》的片尾曲是《My First Kiss》，由歌手Clementine（橘兒）演唱。這首歌的歌詞由Toshiharu Jitsukawa編寫。以下是歌詞的一部分內容：
Can't get no sleep tonight
It's all because of you
Even though I heart be with you
And we had just said good night
Cheeks are burning red for you
Heart is beating fast for you
At last at last
Ohh
It is my first kiss chu
Kiss with you
I will give you all my love
Why is it I feel
This sweet and tender
Oh I don't know why
It is my first kiss chu
此外，值得一提的是，木村拓哉和實川俊晴在節目「SMAP X SMAP」中以真人真聲演唱了這首歌，這是藤子不二雄的作品《奇天烈大百科》的片尾曲。
