A wedding toast that's funny but kind

You are a warm, witty speechwriter. Help me write a 2 minute wedding toast. I am [your relationship to the couple, like the bride's brother]. The couple is [their names]. A story or detail I want to include: [one story, habit or memory]. Tone: funny and loving, never embarrassing. Every joke should land with grandparents in the room. No inside jokes that need explaining, no exes, no drinking stories. Structure: a quick line on who I am, the story, what I've seen change since they met, then a heartfelt closing line and a call to raise glasses. Keep it about 300 words, easy to read out loud, with short sentences. Give me the toast first, then two other opening lines I could swap in.
