The Jurassic Bark episode of Futurama.
I agree 100%. Matt Groening´s works are IMO by far the best recipe for laughter, but this episode was really emotional.
Movies that made my eyes watery:
- Spirited away (you will melt while watching this movie)
- Grave of the fireflies (again, the fantastic studio Ghibli)
- Pursuit of hapiness
- Seven pounds (also staring Will Smith)
- Modern times by Charlie Chaplin (the ending inspires me every time)
- Leon - the professional
- The Elephant man
- it´s a wonderfull life (1945)
- The Pianist
- Schindler´s list
- Casablanca
- embarassed to say, but when watching the 40 year old virgin, it was hard to hold back tears at some scenes where I could painfully relate to the main character
(though it is a comedy and I had a good laugh).
...
I get emotional quite quickly, one of the reasons I prefer watching good movies alone.
