This episode was so funny!!!!! I was cracking up! A Cockamouse! ROFL ROFL. Then Marshall was explaining to everyone about the Cockamouse.. A Cockroach had sex with a mouth ROFL. Oh better yet the Cocapotatoemouse. ROFL ROFL. Marshall throws it outside but the thing can fly! ROFL. Oh look it's coming back!!! ROFL. He closes the window and it hit the window and fell to the ground. ROFL.

Barney really wanted to go to that matchmaker place so bad that he lied to Ted about his boat was sinking. ROFL. Poor Ted there is nobody out there for him. When Ted went to talk to that lady the second time he sounded so desperate.. Another awesome episode!!!!!

Cockamouse ROFL ROFL.

I think it must have been a baby owl.

I was waiting for the "cockamouse" to be revealed to be something innocuous, but I guess the scriptwriters thought it would be hip to let the viewers decide what it must have been.
