Derek and my multilayer puns

[crocodiletears]

[Both people peering into the fish tank at a lone goldfish.]
Derek: I think he's gotten bigger.
Me: You think so?
Derek: Yeah, I think so.
Me: He's not as big as his parents. But they're huge.
Derek: Give him time. I think he's getting bigger.
Me: Might be.
Derek: Might be.
Me: He told me he's starting a cover band.
Derek: Oh yeah?
Me: It's called "I Might Be Giant"
Derek: But they only do Reel Big Fish covers.
