Lightbulb Joke Collection 54
Q: How many post-doctoral fellows does it take to change a lightbulb?
A: One, but it'll probably take three or four tries to get it right because he/she will probably give it to the technician to do.
Q: How many graduate students does it take to screw in a light bulb?
A: Only one, but it may take upwards of five years for him to get it done.
Q: How many graduate students does it take to screw in a light bulb?
A: It all depends on the size of the grant.
Q: How many graduate students does it take to screw in a light bulb?
