Blackberry vs. Blueberry

I had this long meeting with customer today in office. My immediate boss was in the meeting room with me. Then my big boss decided to join us. The meeting went well till at the very end of the meeting, when we wanted to mark our calendar for our next meet up, suddenly my big boss said to me,

“Superlady, can you help me to get my BLUEBERRY on my table.”

I noticed that one of the representatives from my customer’ side (of younger age) smiled upon hearing that. It may not sound funny to you now, but it was at that moment. I really wanna laugh that time but I hold my thought and walked out from the room and laughed outside.

I wonder, is it too confusing to pronounce blackberry and blueberry (because that wasn’t my first encounter)? If yes, can we sue the creator of blackberry (for coming up with such name) for corporate embarrassment? No?
