How blueberry leads to stomach-ache

I just had a terrible stomach-ache. Let me explain...

A few weeks ago we bought a few packets of biscuits/snacks. Among those was a packet of blueberry wafers. There was another flavour too (maybe vanilla, I can't remember), but I chose blueberry. But because we had a number of other things to eat/snack on, I left the packet of wafers unopened to retain its freshness.

Then today I decided to open it. I called out to WW, "Come and eat blueberry wafers!"

Now WW is a big fan of blueberry. He said, "Eh, are there blueberry wafers?" Now I had already mentioned to him that I had bought the wafers (right after buying them), but I guess he wasn't paying attention. And when I showed him the packet, he said, "Huh? It's blueberry? I thought it was pandan!"

But the thing is, the wafers are purple. So I asked him how he could confuse blueberry with pandan (which is green!). Then he said, "Oops, I meant yam!"

Then he continued with "If I had known it was blueberry, I would have opened it myself, and there wouldn't be any left by now! But I thought it was yam, and I don't like yam."

I laughed so hard...and my stomach hurt so hard too.

At least he didn't say "wrong pronunciation".
