When everyone in class wants to die because the teacher is going on and on about things that no one cares about, a fellow finds something that the teacher is saying and uses it to go on a series of uneducational tangents until the class is over.
Example 1:

Teacher: And that is why E=MC^2...

Mullaney: If you judge a fish on it's ability to climb a tree, it will live its whole life believing it is stupid.

Teacher:Why, that is correct, also imagination is more important than knowledge. Actually, I love Albert Einstein, you know class...blah blah blah until the end of class.

*End of class bell* Teacher: Oh, shoot! We're out of time! It seems that I have been caught up in a Mullaney trap!

Example 2:

Student 1: Hey! What do we do in Chem today?

Student 2: I don't know, Dan caught Donndelinger in a Mullaney trap during our class.

Student 1: Fuck, now I don't know if I should do my homework during lunch or not.
