Is it possible to train a dolphin to deliver pizzas without the pizzas getting wet?

Yes. But why would you degrade the dolphin like that? Dolphins are not our slaves. 

Yes they are.

You might be right. 

Would you like fries with that?

Only if they use robot dolphins. Biologic beings are so 2015.

Lol:)

Good point, sunmoonandstars. If the dolphin doesn't want the job, offer it to somebody else. No need to force the dolphin to do it. Lol:)

No, not a dolphin. You would have to use a land shark for that.

Do land sharks bite like sea sharks? Lol:)

You would have to ask the old writers for Saturday Night Live. They used a "land shark" as a running gag for a number of seasons.

Are the old writers still alive? "Saturday Night Live" is very old now.
