I am surprised that noone has mentioned that:
f x
| e = F(u,n)
j
(apologies if someone did post this and I missed it)

Here is another: The integral of dcabin/cabin = logcabin + c = houseboat But the most humorous thing I've seen in this regard is not a formula at all but a beginner's mistake. Having seen that 8/0 is infinity, a student thought that 5/0 is a 5 laid on its side---too bad it is untypable.

How about 8 * sqrt(-1) = infinity (looks better if the "* sqrt(-1)" is written with root signs and juxtaposition, and only works when you replace "infinity" with the usual symbol (not aleph!)). Because a multiplication by i is a rotation through pi/2 radians, don't you know (said in a Peter Wimsey voice) ........................................
