We were coming home on Monday 6-16 on a delayed flight from LGA-BOS. Flight after us had been canceled so ours was full. Alot of people were grumbling (apparently they think delays are new at LGA ) The male FA was making his announcements and started out with "Welcome aboard, our flight time to BOS will be 3 hours 35 minutes and 42 seconds, weather in BOS is 85 degrees and sunny (it was cool and rainy) and then went on with the safety demo and had some fun with that also. He tried to make another announcement and kept tripping over his words, finally he said "oh yeah, we have this on the CD and proceeded to play that. He was amusing and some of us that were actually listening had a few laughs.
